Atomic hydrogen is obtained by catalytic cracking of hydrogen gas on a hot tungsten filament in an ultra-high vacuum chamber. X-ray photoemission spectroscopy, reflection high energy electron spectroscopy, atomic force microscopy, secondary ion mass spectroscopy, and micro-Raman showed that an O- and C-free Ge surface was achieved, while maintaining the same roughness and strain condition of the as-deposited sample and without any Sn segregation, at a process temperature in the 100–300 °C range.}, cin = {PGI-9 / JARA-FIT}, ddc = {530}, cid = {I:(DE-Juel1)PGI-9-20110106 / $I:(DE-82)080009_20140620$}, pnm = {521 - Controlling Electron Charge-Based Phenomena (POF3-521)}, pid = {G:(DE-HGF)POF3-521}, typ = {PUB:(DE-HGF)16}, UT = {WOS:000348998200054}, doi = {10.1063/1.4906616}, url = {https://juser.fz-juelich.de/record/189056}, }
