We report on the non-destructive measurement of Young's modulus thin-film single crystal beta gallium oxide (beta-Ga2O3) out its nanoscale mechanical structures by measuring their fundamental mode resonance frequencies. From measurements, we extract in (100) plane, EY,(100) = 261.4+/-20.6 GPa, for beta-Ga2O3 nanoflakes synthesized low-pressure chemical vapor deposition (LPCVD), and [010] direct...

The aim of this work is to demonstrate the maturity TOPCon technology by conducting a round-robin on symmetrically processed lifetime samples in leading European PV institutes EPFL, ISC, CEA-INES, ISFH, IMEC and Fraunhofer ISE within H2020 funded project called HighLite. For all layers, dark saturation current-densities ranging between 2 10 fA/cm can be reported. Simultaneously, no metal induce...
