Germanium and Germanium Compounds

1990
Abstract Germanium is a semiconducting metalloid element found in Group IV A. Germanium is used in the field of electronics, infrared optics, and in the fields of gamma ray spectroscopy, catalysis, and fiber optics. This article discusses the sources, manufacturing, and processing of germanium, and focuses on the chemical properties of ...

Infrared spectra of germanium sulfide, germanium disulfide, germanium oxide sulfide and germanium dioxide in solid argon

The Journal of Physical Chemistry, 1992
New germanium sulfides, oxides, and mixed sulfide-oxides were prepared from the reaction of elemental sulfur with elemental germanium and oxygen and characterized by infrared absorption spectroscopy. The GeS diatomic product showed absorptions at 564.6, 566.8, 568. 1, 569.2, and 571.7 cm -1 for natural isotopic germanium.

Luminescence from Germanium and Germanium on Silicon

Solid State Phenomena, 2013
We present an overview on generation of direct gap photo- and electroluminescence in Ge bulk wafers, Ge thin films deposited on Si, and Ge p-i-n diodes prepared on Si substrates. We analyzed the emission in a spectral range from 0.45 eV to 0.95 eV, covering the radiation caused by direct gap transitions, the indirect one, and also the luminescence ...

Synthesis of Antimonene on Germanium

Nano Letters, 2017
The lack of large-area synthesis processes on substrates compatible with industry requirements has been one of the major hurdles facing the integration of 2D materials in mainstream technologies. This is particularly the case for the recently discovered monoelemental group V 2D materials which can only be produced by exfoliation or growth on exotic ...

Amorphous germanium contacts on germanium detectors

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2005
Abstract The rectification properties of sputtered amorphous germanium contacts made under a variety of conditions on germanium detectors have been measured as a function of temperature and electric field. The leakage current increased as a function of voltage above depletion voltage. The rectifying amorphous–crystalline heterojunction theory derived

Stable germanium dioxide films on germanium

Solid-State Electronics, 1972
Abstract When SiO 2 is deposited on a germanium wafer as a protective film, the oxidation of germanium is not prevented when the wafer is annealed in oxygen at temperatures of 600 to 800°C. However, the conversion of germanium into GeO is prevented.
