چکیده
We report on the growth and characterization of Ge-doped \b{eta}-Ga2O3 thin films using a solid germanium source. were grown low-pressure chemical vapor deposition (LPCVD) reactor with either an oxygen or gallium delivery tube. Films 6 degree offcut sapphire (010) substrates rates between 0.5 - 22 {\mu}m/hr. By controlling pressure, wide range Hall carrier concentrations 10^17 10^19 cm-3 achieved. Low-temperature data revealed difference in donor incorporation depending configuration. At low rates, occupied single energy level 8 10 meV. higher doping predominantly results deeper at 85 This work shows effect design regime kinetics impurity incorporation. Studying is important for high-power electronic devices.

n-Type Doping of Vapor–Liquid–Solid Grown GaAs Nanowires
In this letter, n-type doping of GaAs nanowires grown by metal-organic vapor phase epitaxy in the vapor-liquid-solid growth mode on (111)B GaAs substrates is reported. A low growth temperature of 400°C is adjusted in order to exclude shell growth. The impact of doping precursors on the morphology of GaAs nanowires was investigated. Tetraethyl tin as doping precursor enables heavily n-type doped...
متن کاملVapor Phase Doping with N-type Dopant into Silicon by Atmospheric Pressure Chemical Vapor Deposition
Atomic layer doping of phosphorus (P) and arsenic (As) into Si was performed using the vapor phase doping (VPD) technique. For increasing deposition time and precursor gas flow rate, the P and As doses tend to saturate at about 0.8 and 1.0 monolayer of Si, respectively. Therefore, these processes are self-limited in both cases. When a Si cap layer is grown on the P-covered Si(001), high P conce...
متن کاملLow-temperature growth of highly crystalline β-Ga2O3 nanowires by solid-source chemical vapor deposition
UNLABELLED Growing Ga2O3 dielectric materials at a moderately low temperature is important for the further development of high-mobility III-V semiconductor-based nanoelectronics. Here, β-Ga2O3 nanowires are successfully synthesized at a relatively low temperature of 610°C by solid-source chemical vapor deposition employing GaAs powders as the source material, which is in a distinct contrast to ...
