PXT992 Advanced Study and Research Skills Research Project Pitch (Poster) Assessment summary and instructions Criteria: 5 Marks: 100 Assessment: Your submission will be assessed against explicitly the stated assessment criteria. Submission: Please upload your poster document in its native file format to the OneDrive folder corresponding to your PXT992 group. To be clear, this is an individual submission, but the files are being grouped together on OneDrive for logistical purposes. Marks available 1 Presentation and clarity of the poster document 20 2 Demonstration of purpose 20 3 Effective presentation of the scientific background and wider scientific context 20 4 Effective presentation of the proposed research project methodology 20 5 Effective presentation of the proposed research project structure 20Summary The ability to summarise academic research or a research plan in a succinct and compact form is an essential skill for practising scientists. Posters, short talks, and videos are common formats for this kind of communication. As part of this module's Virtual Conference. you are required to pitch your research plan in the form of either a poster or a short video. This script covers the requirements for poster submissions. Please remember that this exercise is a pitch. This is a slightly different form of presentation compared to summaries and reports. You are expected to be able to convince the audience of the value and achievability of your proposed research project. You should consider carefully your experience with generating posters and videos from your activities on the MSc and more widely. You should choose the format which aligns most strongly with your skillset. There is no \"preferred" submission format - it is possible to score full marks for either a poster or a video if the assessment criteria are met to the required standard. Submission requirements Poster document You must generate a single page document in a 15:9 ratio and with landscape orientation. The poster must be comfortably viewable at A1 size and a viewing distance of 1 metre. The layout of the poster is up to you. Consider carefully the best use of space. The poster's content need not be static. Animations and other dynamic content are permitted. The tone of the poster must be formal and scientific. HBDBCII LI I I"I UJL'JLL I'ILbI I {I'UDLUIJ Assessment criteria Criterion i: presentation and ciarity of the poster document The poster document must effectively communicate the important aspects of your research project plan and convince the audience of the value and achievability of your proposed research project as a standalone submission. Remember that there will be no opportunity to respond to questions. Ensure that your poster document: Clearly displays the proposed research project title, your name, and your affiliations. ls implemented as a single page 15:9 aspect ratio document in landscape orientation which is clearly readable at A1 size at a viewing distance of 1 metre. Clearly and concisely describes the scientic background to the proposed research project. Establishes the proposed research project in the wider scientific context. Clearly and concisely describes the proposed research project methodology. Clearly presents and summarises the main points of the proposed research project structure. Uses formal scientific English throughout, with effective use of graphs, images, animations, etc., as appropriate to the topic of the micro project. Criterion 2: demonstration of purpose The poster document taken as a whole should clearly demonstrate the research projects purpose. Ensure that you state a clear and succinct set of research questions which motivate the research project. It is strongly recommended that you present a hierarchically-structured set of aims and objectives. Note that you are not expected to go into the same level of detail as the written project plan; the poster should contain only the most important points. Criterion 3: effective presentation of the scientific background and wider scientific context The poster document should summarise the scientic context in order tojustify the project as worthwhile and to provide motivation for the project's viability. You should include some critical appraisal of the uncertainties i difficulties i risks associated with the proposed project in light of the established literature. Note that you are not expected to go into the same level of detail as the written project plan; the poster should contain only the most important points. Criterion 4: effective presentation of the proposed research project methodoiogy The poster document should summarise the proposed research project methodology. Note that you are not expected to go into the same level of detail as the written project plan; the poster should contain only the most important points. Criterion 5: effective presentation of the proposed research project structure The poster document should summarise proposed activities, major milestones and possible branching points. The research project structure should clearly and unambiguously address the research questions. You should include some critical discussion of practical considerations. the timing and dependency of activities, and major logistical risks. Note that you are not expected to go into the same level of detail as the written project plan ; the poster should contain only the most important points. Characterisation of Antimony Containing Type-II Superlattices Grown Via MOCVD For Infrared Detection Richard Brown Cardiff University Abstract Type-II Superlattices MOCVD Growth of Antimony The Project - Characterisation of T2SL Samples Infrared devices play an important role in cutting edge applications The type-II superlattice (T2SL) was first discovered in 1977 and was published in the Up until this point, antimony containing T2SLs have mostly been produced via The project can be broken down into 3 aims; including high-speed data communication, Light Detection and Ranging seminal paper from the IBM T. J. Watson Research Center. A superlattice is a molecular beam epitaxy (MBE). This is due to the ability of MBE to produce very pure, . Characterisation training (LIDAR), thermal imaging and biomedical sensing. In order to improve structure in which alternating layers of semiconductor are stacked on top of each atomically sharp and precisely thick growth layers. However, MBE is slow and Characterising the samples device performance for these and other vital technologies new materials other creating a structure that acts like a 'bulk' material with its own band gap based expensive and so if antimony containing T2SLs are to become the mainstream . Preposing improvements and recording findings must be developed to overcome the weaknesses of the currently used on its stack structure. A T2SL consists of a bilayer semiconductor stack where the replacement to bulk HgCdTe a different growth method is required. The most technology.

The separation of the bands between the two materials of the superlattice means Improvement in our infrared device capabilities is vital for the development of modern society Infrared sensing applications the positions of the conduction band and valence band can be tuned independently The low equilibrium vapor pressure of antimony is another major difficulty as it and that journey starts at the material level. The antimony based type-Il superlattice is a very This allows for a very high degree of band engineering. The band gap of the T2SL can causes antimony crystals to form if the ratio of the group-Ill and group-V sources is promising material set to reshape the world of infrared sensing, once manufacturing be made smaller than the band gap of the individual semiconductor material making not accurately maintained, as shown in figure (4). constraints are overcome.
