“…Passivation of the Cd dopant by the formation of Cd-H pairs is known in indium arsenide. 79 However, As-H is a much stronger bond (582 kJ mol -1 ) than any of Hg-H, Cd-H or Te-H and on prolonged annealing such as the 4 h anneals described earlier, the hydrogen bonded to the matrix elements is likely to move to and bond with As to form As-H, i.e., internal passivation. This is supported by comparison of Figs.…”

Acceptor doping of many II-VI compound semiconductors has proved problematic and doping of epitaxial mercury cadmium telluride (MCT, Hg 1-x Cd x Te) with arsenic is no exception. High-temperature (>400°C) anneals followed by a lower temperature mercury-rich vacancy-filling anneal are frequently required to activate the dopant. The model frequently used to explain p-type doping with arsenic invokes an amphoteric nature of group V atoms in the II-VI lattice. This requires that group VI substitution with arsenic only occurs under mercury-rich conditions either during growth or the subsequent annealing and involves site switching of the As. However, there are inconsistencies in the amphoteric model and unexplained experimental observations, including arsenic which is 100% active as grown by metalorganic vapor-phase epitaxy (MOVPE). A new model, based on hydrogen passivation of the arsenic, is therefore proposed.

“…Since the late 1980s many PAC experiments have been carried out on hydrogen in Si [183][184][185] and III-V semiconductors [119,120,122,[186][187][188][189][190][191][192] and a considerable amount of new information could be obtained concerning formation, microscopic structure and stability of acceptor hydrogen complexes. PAC studies on acceptor-hydrogen interactions require a doping of the material with probe atoms, which represent acceptor impurities in the corresponding semiconductor.…”

“…In the early 1990s the application of radioactive atoms in solid state physics experienced a new boost. Initiated by the pioneering experiments of Petersen [16] a new category of radiotracer techniques was established by combining traditional semiconductor physics methods like deep level transient spectroscopy (DLTS) [16,17], capacitance voltage measurements (CV) [18,19], Hall effect (HE) [20], photoluminescence spectroscopy (PL) [21][22][23] or electron paramagnetic resonance spectroscopy (EPR) [24,25] with radioactive isotopes. These powerful techniques are widely used, not only at universities and research institutions but also in industrial laboratories as well, to investigate the structural, electronic and optical properties of point defects in semiconductors.…”

Radioactive atoms have been used in solid state physics for many years. Established nuclear techniques such as Mößbauer spectroscopy, perturbed angular correlation, β-NMR and emission channelling have now been joined by new and successful tracer techniques like radioactive deep level transient spectroscopy, capacitance voltage measurements, Hall-effect measurements or photoluminescence spectroscopy. Numerous radioactive species, ranging from 8 Li to 213 Fr, are employed to attack problems involved with defects or impurities in metals, semiconductors and superconductors.This paper aims to give an idea of the potential of modern 'radioactive solid state physics' by briefly explaining the techniques used and describing some typical experiments.

The use of radioactive beams in solid state physics has become more and more popular during the past few years, and both off-line and on-line mass separators are used for implanting various types of radioactive isotopes into the material under investigation. Besides the nuclear techniques of Mössbauer spectroscopy, perturbed angular correlation spectroscopy, β-NMR, or the ion-beam technique of emission channelling, a new group of radiotracer techniques has been established, which combines radioactive probe atoms with conventional semiconductor physics methods such as deep-level transient spectroscopy, capacitance-voltage measurements, Hall-effect measurements, or photoluminescence spectroscopy.This paper aims to give an idea of the potential of modern 'radioactive solid state physics' by describing some typical experiments.
