Question:

Graphite is a semimetal with a band structure of the type shown in Fig. 4.70. Reaction of graphite with potassium produces C₈K while reaction with bromine yields C₈Br. Assuming the graphite sheets remain intact and potassium and bromine enter the graphite structure as K⁺and Br⁻ ions, respectively, discuss whether you would expect the compounds C₈K and C₈Br to exhibit metallic, semimetallic, semiconducting, or insulating properties.
