PROPERTIES OF GALLIUM SELENIDE SINGLE-CRYSTAL

GaSe appears to be a possible candidate material for optical frequency conversion in the near to far infrared (1-18 mu m) wavelength. Various properties of this material are important to researchers and systems designers to assess the utility of this mterial and to develop applications. A search of the published literature amassed over 630 articles. An attempt was made to organize this material by growth, structural and mechanical, thermal, electrical and optical properties. More effort was made to condense thermal and optical properties along with accounts of nonlinear optical (NLO) usages. A summary of the good and bad properties for NLO applications is given.
