Terahertz probe of carrier trapping in polymer transistors
Optics InfoBase Conference Papers (2007)
Abstract:
The trapped charge density at the polymer-insulator boundary of polymer transistors was monitored by terahertz time-domain spectroscopy. Additionally, the thermal removal of trapped holes and the light-induced transmission change were studied. © 2006 Optical Society of America.Transmission and emission terahertz time-domain spectroscopy with polarisation-sensitive photoconductive receivers

Abstract:
In this contribution a detailed characterisation of the performance of three-contact polarisation-sensitive terahertz detectors will be discussed. Furthermore the appropriate mathematical formalism required for the analysis of polarisation-resolved THz measurements will be presented. In addition, measurements of the polarisation-resolved transmission of quartz and polarisation-resolved emission of (110) ZnTe will be shown in order to illustrate the relevance of polarisation in time domain measurements. Finally perspectives on experiments that require polarisation sensitivity will be discussed.Compound semiconductors for terahertz photonics

Abstract:
Terahertz photonics is a rapidly growing field. The ultra-fast dynamics of charge carriers in semiconductors is closely linked to the performance of THz photonic devices. We study a range of ion-implanted and nano-scale semiconductors for application in novel terahertz devices.Conductivity of nanoporous InP membranes investigated using terahertz spectroscopy
