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. Variou s properties of this material are important to researchers and systems designers to assess the utility of this mterial and to develop applic ations. 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 effor t was made to condense thermal and optical properties along with accou nts of nonlinear optical (NLO) usages. A summary of the good and bad p roperties for NLO applications is given.
