de Vrijer, T. (author), van Dingen, Julian E.C. (author), Roelandschap, Paul J. (author), Roodenburg, Koos (author), Smets, A.H.M. (author)Amorphous and nano-crystalline germanium is of potential interest for a wide range of electronic, optical, opto-electronic and photovoltaic applications. In this work the influence of deposition temperature on hydrogenated germanium (Ge:H) films was characterized, using over 200 Ge:H and over 70 SiGe:H films. The demonstrated temperature...journal article 2022

(author), Saitta, F.S. (author), Blackstone, Thijs (author), Smets, A.H.M. (author)In this paper the opto-electrical nature of hydrogenated group IV alloys with optical bandgap energies ranging from 1.0 eV up to 2.3 eV are studied. The fundamental physical principles that determine the relation between the bandgap and the structural characteristics such as material density, elemental composition, void fraction and...journal article 2022
