Kinetics, thermodynamics, and catalysis of the cation incorporation into GeO2, SnO2, and (SnxGe1-x)O2 during suboxide molecular beam epitaxy
Wenshan Chen, Kingsley Egbo, Joe Kler +3
Rutile GeO is a promising ultra-wide bandgap semiconductor for future power electronic devices whose alloy with the wide bandgap semiconductor rutile-SnO enables bandgap en…
Phase-selective growth of - vs -GaO and (InGa)O by In-mediated metal exchange catalysis in plasma-assisted molecular beam epitaxy
A. Ardenghi, O. Bierwagen, J. Lähnemann +4
Its piezo- and potentially ferroelectric properties make the metastable kappa polymorph of GaO an interesting material for multiple applications, while In-incorporation int…
Acceptor and compensating donor doping of single crystalline SnO (001) films grown by molecular beam epitaxy and its perspectives for optoelectronics and gas-sensing
Kingsley Egbo, Jonas Lähnemann, Andreas Falkenstein +2
(La and Ga)-doped tin monoxide (stannous oxide, tin (II) oxide, SnO) thin films were grown by plasma-assisted and suboxide molecular beam epitaxy with dopant concentrations ranging…
Towards controllable Si-doping in oxide molecular beam epitaxy using a solid SiO source: Application to -Ga2O3
A. Ardenghi, O. Bierwagen, A. Falkenstein +4
The oxidation-related issues in controlling Si doping from the Si source material in oxide molecular beam epitaxy (MBE) is addressed by using solid SiO as an alternative source mat…
Anisotropic Microgels show their Soft Side
Anne C. Nickel, Timon Kratzenberg, Steffen Bochenek +6
Anisotropic, submicrometer sized particles are versatile systems providing interesting features in creating ordering in 2-dimensional systems. Combining hard ellipsoids with a soft…
Offcut-related step-flow and growth rate enhancement during (100) -Ga2O3 homoepitaxy by metal-exchange catalyzed molecular beam epitaxy (MEXCAT-MBE)
Piero Mazzolini, Andreas Falkenstein, Zbigniew Galazka +2
In this work we investigate the growth of -Ga2O3 homoepitaxial layers on top of (100) oriented substrates via indium-assisted metal exchange catalyzed molecular beam epitaxy (ME…
Isotopic study of Raman active phonon modes in -GaO
Benjamin M. Janzen, Piero Mazzolini, Roland Gillen +5
Holding promising applications in power electronics, the wide band gap material gallium oxide has emerged as a vital alternative to materials like GaN and SiC. The detailed study o…
