Abstract
(English)
Nominally undoped Ge epitaxial layers were deposited on Ge and GaAs substrates by means of Metal–Organic Vapor Phase (MOVPE) using a novel Germanium source, isobutylgermane (iBuGe), by Rohm and Haas Electronic Materials LLC (USA). High Resolution X-ray Diffraction, Atomic Force Microscopy and Raman spectroscopy were combined to characterize the layers. Ge layers were deposited using AsH3 as a surfactant and several growth procedures were tested. The use of arsine reduced the growth rate and also significantly improved the epitaxial quality and surface roughness.
