Ambient stability of wet chemically passivated germanium wafer for crystalline solar cells
Surface passivation has been recognized as a crucial step in the evaluation of minority carrier lifetime of photovoltaic materials as well as in the fabrication of high efficient solar cells. Dilute acids of [...]
AlGaN template structure report
A test report is necessary to show the compliance between custom description and our final wafers data. We will test the wafer characerization by equipment before shipment, testing surface roughness by atomic force microscope, type by Roman spectra instrument, resistivity by [...]

AlN thin film, as a piezoelectric material with a wurtzite structure, has attracted much attention due to its excellent performance. However, compared with other piezoelectric materials such as Pb (ZrxTi1-x) O3 (lead zirconate titanate, PZT), pure AlN thin films exhibit poorer piezoelectric response. Doping [...]
