Every published study of higher manganese silicide (HMS) that has been concerned with its electronic band structure has affirmed its semiconducting nature. The results fall into two main camps: (1) it has a direct bandgap near 0.7 eV, or (2) it has a

Knowing the fundamental trends of sputter yield in the sputtering regime used for film deposition is crucial for understanding the mechanisms of sputter deposition, interpreting yield data, and predicting the results of experiments. One source of exp

The authors have recently added a strong writing component to one of their freshman courses in electrical engineering. The students prepared two kinds of reports-memoranda and formal engineering project reports. The authors' instructional objectives

Reactive deposition of magnesium onto a hot silicon substrate (200–500°C) does not result in any accumulation of magnesium or its silicide — the condensation coefficient of magnesium being zero. On the other hand, co deposition of magnesium with

Thin film deposition by sputtering is usually performed with projectile-energy-target combinations placing the sputtering mechanism within the linear cascade regime of collisional sputtering. For the purposes of estimating sputter yield values, as we

yield (;30%) is as low as that of state-of-the-art bulk material, and the interface is atomically abrupt. The initial film deposits are epitaxial islands, and subsequent growth is in the Frank‐van der Merwe mode. With the islands already relaxed at

${\mathrm{Mg}}_{2}$Si is a semiconductor with a band gap previously reported to be in the range 0.6--0.8 eV. In spite of potential optoelectronic applications in an important infrared range, the growth of ${\mathrm{Mg}}_{2}$Si thin films on silicon s

Vacuum evaporation techniques were applied to the epitaxial growth of CrSi2 on Si(111) substrates. There are two CrSi2 matching faces which offer good lattice matchings, and which are observed experimentally: the (001) and the (111). These are presen

Reactive deposition epitaxy was used to synthesize thin layers of RexMo1−xSi2 on Si(100). In the case of x=1, ReSi2 layers of excellent crystalline quality have been reported previously [J. E. Mahan, K. M. Geib, G. Y. Robinson, R. G. Long, Y. Xingh

Carbon contamination of silicon surfaces is a longstanding concern for growers of thin films who utilize silicon wafer substrates. This contamination often takes the form of epitaxial β‐SiC particles which grow after the decomposition of adsorbed
