Description

Description Used for the growth of GaAs/AlGaAs/InGaAs semiconductor heterostructures doped n-type with silicon and p-type with beryllium also used for the growth of self organised In(Ga)As quantum dots and pillars. The system has a specific emphasis on growing microwave and terahertz components especially quantum cascade lasers. Material is supplied to a range of international collaborators including Harvard University, University of Texas, Paris Sud, Paris 7, Ecole Normale superiure, University of Vilnius. Typical structures are highlighted in: Papers Barbieri, S; Ravaro, M; Gellie, P; Santarelli, G; Manquest, C; Sirtori, C; Khanna, SP; Linfield, EH; Davies, AG Coherent sampling of active mode-locked terahertz quantum cascade lasers and frequency synthesis.
