By employing a mixed SnO2 + Sn source, we demonstrate suboxide molecular beam epitaxy (S-MBE) growth of phase-pure single-crystalline metastable SnO (001) thin films on Y-stabilized ZrO2 (001) substrates at a growth rate of ∼1.0 nm/min without the need for additional oxygen. These films grow epitaxially across a wide substrate temperature range fro...
By employing a mixed SnO$_2$+Sn source, we demonstrate suboxide molecular beam epitaxy growth of phase-pure single crystalline metastable SnO(001) thin films at a growth rate of ~1.0nm/min without the need for additional oxygen. These films grow epitaxially across a wide substrate temperature range from 150 to 450{\deg}C. Hence, we present an alter...
Gallium oxide is a promising candidate for several future electronic devices to replace common technologies. For this reason, an understanding of fundamental physical processes is needed. In this work, we investigate the Raman excitations of a α-Ga2O3 thin film under temperature variation from 80 K up to 790 K. This yields detailed information abou...
