Assessment of doped CdxHg1-xTe structures using bevelled sections

Abstract
Doped homo- and heterostructures of CdxHg1-xTe (CMT) are required for some types of new-generation devices. These structures have been grown by metal organic vapour phase epitaxy (MOVPE) at approximately 360 degrees C onto both CdTe and GaAs (buffered with CdTe) substrates. The structures were produced using both acceptor and donor doping with arsenic and iodine respectively, and the junctions formed following annealing in mercury to eliminate metal vacancies. This paper summarizes progress in characterizing these junctions both in terms of x and electrical behaviour.
