摘要
We report high performance single-grain Ge TFTs by mu-Czochralski process. Electron mobilites are 3337cm(2)/Vs with on/off ratio of 10(8) @V-DS=0.1V. Hole mobilities are 1719cm(2)/Vs with on/off ratio of 10(8) @ V-DS=0.05V. The high mobility is due to improved interface property and tensile stress.
