II–VI semiconductor multilayers, containing a quantum well (ZnTe/CdTe/ZnTe or Cd0.6Hg0.4Te/HgTe/CdTe) have been implanted with Zn+ or Cd+ ions at different fluences and temperatures, and analyzed by Rutherford backscattering spectroscopy and channe

A molecular beam epitaxy (MBE) system used for epitaxial growth of rare earth (Eu, Sm and Nd) compounds on CdTe is described. Owing to the high reactivity of the films, it appeared fruitful to connect this apparatus to a 2.5 MeV van de Graaff acceler

Implantation‐enhanced interdiffusion of CdTe‐ZnTe strained heterostructures is studied by photoluminescence, channeling, transmission electron microscopy, and secondary‐ion‐mass spectrometry. In the tellurides, implantation defects significan

An interfacial layer (IL), about a nanometer thick, is produced by Sm deposition onto (001) CdTe grown by molecular‐beam epitaxy. This IL is studied by reflection high‐energy electron diffraction (RHEED), ion channeling, and x‐ray diffraction.

Recently, a new method using carbon implantation at 300 K in bulk copper followed by excimer laser annealing has been proposed to synthesize diamond, with contradictory results. We use this technique on copper thin films with carbon implantation at 7

It is shown that the deposition of Sm, Nd and Eu onto [001] CdTe results in the formation of an epitaxial rare-earth telluride layer. In the case of Sm and Nd, this layer acts as an efficient diffusion barrier allowing further epitaxial growth of met

Implantation-enhanced interdiffusion in CdTe/ZnTe quantum wells (QWs) has been studied using photoluminescence and secondary ion mass spectroscopy. In this system, a strong compositional disorder is produced by implantation alone. This is attributed

We want to review recent structural investigations of the heteroepitaxial interfaces between II-VI semiconductors deposited by Molecular Beam Epitaxy and GaAs substrates. The structure of the relaxed interfaces will firstly be dealt with by reference

Ni-P alloys were formed by P ion implantation into pure Ni single crystals at low (15 K) and high (300 K) temperature up to a metalloid ion concentration (≈0.12) such that the fractions of amorphous volume obtained at the maximum disorder depth wer
