High quality hydrogenated amorphous germanium prepared by the hot wire technique

Applied Physics Letters, 1995
Hydrogenated amorphous germanium films were deposited by thermal dissociation of undiluted germane. The optical and electronic properties of the material were investigated using infrared spectroscopy (IR), photothermal deflection spectroscopy, spectroscopic ellipsometry, and conductivity measurements.

A simple automated hot-wire positioning technique for near-wall measurements

Experiments in Fluids, 1993
A simple hot-wire sensor positioning technique is presented. The technique is easily integrated with a personal computer to achieve a completely automated system. A single initial calibration of the system outside of the test section is all that is necessary and no subsequent manual re-positioning is required during experimentation.

Nanocrystalline Undoped Silicon Films Produce by Hot Wire Plasma Assisted Technique

MRS Proceedings, 2000
ABSTRACTIn this work, we show results concerning electro-optical properties, composition and morphology of nanocrystalline hydrogenated undoped silicon (nc-Si:H) films produced by hot wire plasma assisted chemical vapour deposition process (HWPA-CVD) and exhibiting a compact granular structure, as revealed by SEM micrographs.

The Preparation of High-Purity Boron by Hot-Wire Techniques

1960
Techniques are described for preparing massive, 99.9+% pure boron in 100-g quantities by hydrogen reduction of boron tribromide vapor on tantalum filaments at 1450°C. Deposition rates up to 9 g/hr, with better than 90% recovery of boron from the tribromide, were obtained. Under optimum conditions, the impurity levels in parts per million in the product

A Computer-Assisted Hot Wire Technique for Measuring Oscillating Velocity Profiles

The Journal of the Acoustical Society of America, 1974
The need for detailed knowledge of conditions at the interface of the free stream at the mouth of a cavity resonator has led to the development of a computer-assisted technique for velocity profile measurement. Basically, hot wire data are recorded simultaneously with sound pressure microphone data so as to permit later sorting out: of local velocity ...
