Use of hydrogenation in the study of the properties of amorphous germanium tin alloys

Abstract
A study of the macroscopic properties of a‐Ge:Sn and a‐Ge:Sn:H films is presented. The samples were prepared by the rf sputtering method on substrates held at 180 °C. Their composition and structure were characterized, and the transport and optical properties were studied. The role and influence of hydrogen on the general properties of the alloys have been established.
