Abstract:

In recent years carbon based devices are exploited for a wide range of applications related to electronics and optoelectronics, due to their unique electrical, optical and mechanical properties. Many sensors, emitters, transistors and logic devices use carbon nanotubes as their major building block. Here we present a technology for inkjet printing of a hybrid tunable detector composed of carbon nanotubes and nanocrystals. The printing can be performed on flexible elastic transparent substrates, as well as on a rigid semiconductor or dielectric substrates. The presented detector is low cost, operates at room temperature and can be printed easily in a large format. We show that these types of sensor function with high quantum efficiency due to a gating effect induced by the light excitation.
