Abstract

Si/Si_1-x-yGe_xC_y/Si quantum well heterostructures grown by UHVCVD have been characterized in terms of structural and optical properties. The Schottky barrier height (SBH) and ideality factor of PtSi/p-Si_1-x-yGe_xC_y/Si diodes have been investigated using the current-voltage characteristics. The valence band offsets of Si/Si_0.795Ge_0.2C_0.005 and Si/Si_0.79Ge_0.2C_0.01 have been extracted using the Schottky diode measurements. A lower value of SBH has been observed in the ternary alloy compared to those in fully strained-Si_1-xGe_x films indicating the potential of former for long wavelength IR detection.
