Spray Coating of Two-dimensional Suspended Film of Vanadium Oxide Coated Carbon Nanotubes for Fabrication of Large Volume Infrared Bolometer.

A novel spray coating and transfer method is developed for fabricating suspended bolometer device of vanadium oxide coated multiwalled carbon nanotubes (VCNT). Parametric study was performed to evaluate the effect of substrate, modulation frequency and temperature on the bolometric performance of the device and revealed that the performance of the device solely does not depend on the substrate parameter, but modulation frequency and bias current as function of temperature also play a key attribute. The TCR (temperature coefficient of resistance) of the suspended VCNT device is ~-0.41%/K which is ~486% higher that the reported suspended multiwalled carbon nanotubes at 300 K. Moreover, suspended bolometric device has a voltage responsivity of ~67.42±5.46 V/W (~7.68 times that of unsuspended device) at 200 K. Thus, the study presents an efficient method to develop suspended bolometric device that has not been realized so far to obtain much higher TCR and responsivity.
