A compound semiconductor is a semiconductor compound composed of chemical elements of at least two different species. These semiconductors form for example in periodic table groups 13–15 (old groups III–V), for example of elements from the Boron group (old group III, boron, aluminium, gallium, indium) and from group 15 (old group V, nitrogen, phosphorus, arsenic, antimony, bismuth).
Gallium arsenide was first synthesized and studied by Victor Goldschmidt and his co-partner Donder Vwishuna in 1926 by passing arsenic vapors mixed with hydrogen over gallium(III) oxide at 600 °C. [ 7 ] [ 8 ] The semiconductor properties of GaAs and other III-V compounds were patented by Heinrich Welker at Siemens-Schuckert in 1951 [ 9 ] and ...
China announced Tuesday it is banning exports to the United States of gallium, germanium, antimony and other key high-tech materials with potential military applications, as a general principle ...
