摘要

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