Investigation of the tunneling emitter bipolar transistor as spin-injector into silicon
… study on scattered and secondary electrons in e-beam evaporation is described. Spin-orbit coupling induced spin-interference of ring-structures is proposed as a spin-detector. A new measurement technique to probe bias dependent magnetic noise in magnetic tunnel junctions is proposed. Also, an IV …

Contact resistance study on polycrystalline silicon thin-film solar cells on glass
… (poly-Si) thin-film solar cells on glass using e-beam evaporation technology. We believe our solar cells have the potential of significantly lowering the manufacturing cost compared to conventional, PECVD-fabricated thin-film solar cells. After years of materials research, the focus of the Group’s …

HfO2 as gate dielectric on Si and Ge substrate
… as gate dielectric deposited by standard thermal evaporation and e-beam evaporation on Si and Ge substrates were investigated. The dielectric constant of HfO_2 deposited by thermal evaporation on Si is in the range of 18-25. Al/HfO_2/Si MOS capacitors annealed at 450 C show low hysteresis, leakage …
