Question:

Vanadium oxides are of interest for various sensor applications, owing to the sharp metal–insulator transitions they undergo as a function of temperature, pressure, or stress. Vanadium triisopropoxide (VTIPO) was used to grow vanadium oxide films by chemical vapor deposition (J. Electrochem. Soc., 136, 897 (1989)). The deposition rate as a function of VTIPO pressure for two different temperatures follows. T = 120°C: Growth Rate (um/h) 0.004 0.015 0.025 0.04 0.068 0.08 0.095 0.1 VTIPO Pressure (torr) 0.1 0.2 0.3 0.5 0.8 1.0
