Abstract

We show that a carbon nanotube (CNT) diode fabricated by asymmetric contacts shows a linear photocurrent in response to illumination for over six decades or dynamic range of 120 dB; in particular, it shows no sign of degradation under illumination intensity of up to 100 kW/cm(2). This CNT diode also exhibits a continued response for incident wavelength from 1165 nm to 2100 nm, promising potentials applications in robust and wide bandwidth light sensing.
