THz Radiation Source Through Periodically Modulated Structures

Abstract

In the time period since the last report we have concentrated our activities in measuring plasmon replicas in low doped bulk GaAs using the technique of hot electron spectroscopy. For this purpose a new four terminal device was fabricated and tested. The IV curves are very promising and show some pronounced features which have to be analysed together with theoretical calculations. In addition we have concentrated our efforts on new specially designed structures together with the Boston group to achieve strong population inversion. Design and subsequent growth of a series of nanostructures with appropriate injector-extractor arrangements for two different doping levels was realised.
