Unleashing Giant TCR from Phase Changes in Carbon Nanotube Composites

摘要

We present a new material platform for uncooled bolometric infrared detection, consisting of a composite membrane of carbon nanotubes and a non-conductive, volume phase-change polymer. Devices using this platform have achieved temperature coefficients of resistance (TCR) in excess of - 40%/K at 300 K, an order of magnitude larger than commercial materials.
