Effect of ethanol vapour sorption on the semiconductor-metal phase transition in powdered vanadium dioxide

نویسندگان

چکیده

We studied the effect of ethanol vapour on parameters semiconductor-metal transition in a polycrystalline vanadium dioxide powder stable monoclinic phase a-VO2. It was synthesised by reducing pentoxide with oxalic acid while heated air. The DC electrical resistance samples between room temperature and 100оС tubular heater, microcompressor-generated air stream saturated ethyl alcohol vapour. found that presence vapour, hysteresis loop shifted to higher temperatures ten degrees its cooling branch (corresponding from metallic semiconductor phase) became stepped.

Compact silicon photonic waveguide modulator based on the vanadium dioxide metal-insulator phase transition.

We have integrated lithographically patterned VO2 thin films grown by pulsed laser deposition with silicon-on-insulator photonic waveguides to demonstrate a compact in-line absorption modulator for use in photonic circuits. Using single-mode waveguides at lambda=1550 nm, we show optical modulation of the guided transverse-electric mode of more than 6.5 dB with 2 dB insertion loss over a 2-micro...
