Abstract

Thin films (4-150 nm) of metallic LiMo3Se3 nanowires respond to chemical vapors of molecular analytes (2-400 mTorr) with rapid (<20 s) and mostly reversible changes of their resistance (DeltaR/R0 approximately 1-70%). Measurements show that the effect is concentration-dependent, and that it depends on the molecular properties of the analytes.

摘要

金属LiMo3Se3纳米线的薄膜（4 - 150纳米）对分子分析物的化学蒸汽（2 - 400毫托）作出响应，其电阻会迅速（<20秒）且大多可逆地变化（ΔR/R0约为1 - 70%）。测量结果表明，该效应与浓度有关，并且取决于分析物的分子特性。
