Epitaxial narrow gap PbSe is grown by MBE (molecular beam epitaxy) onto Si(111) substrates with the aid of a BaF 2 /CaF 2 buffer layer. The tensile strain which builds up on cool-down after growth due to the thermal expansion mismatch is relaxed by c

The thermal mismatch strain in stacks containing PbSe, ${\mathrm{BaF}}_{2}$, and/or ${\mathrm{CaF}}_{2}$ on Si(111) substrates is relieved by the glide of dislocations in the principal 〈110〉{100} glide system. The strain in the ${\mathrm{BaF}}_{2

The thermal mismatch strain introduced by the different thermal expansion of fluorides, IV-VI materials and the Si(111) substrate is relieved by glide of dislocations in the primary {100}〈110〉 glide system with glide planes inclined to the surfac

Metalorganic vapor phase epitaxy has been used for the first time to grow epitaxial GaAs layers on (111) and (100) oriented Si either using CaF2 or stacked (Ca,Sr)F2/CaF2 as a buffer. The GaAs layers show sharp and well resolved electron channeling p

Epitaxial narrow gap lead chalcogenide layers were grown on Si-substrates with the aid of an intermediate epitaxial CaF2-BaF2 buffer by molecular beam epitaxy. Maximum growth temperatures were as low as 450°C both for the buffer and lead chalcogenid

The strain induced by the thermal mismatch in Pbl−xSnxSe and other IV–VI compound layers on Si(111)-substrates relaxes by glide of dislocations in the main {001}-glide system. The glide planes are arranged with 3-fold symmetry and inclined to the

Epitaxial narrow gap IV-VI layers on Si-substrates offer an alternate to Hg1−xCdxTe for IR-focal plane arrays with similar ultimate sensitivities. We report on the following improvements in reaching the goal of an easily producible fully monolithic
