摘要

We have demonstrated Si/Ge hole-tunneling double-barrier resonant tunneling diodes (RTDs) formed on flat Ge layers with a relaxation rate of 89% by our proposed method; in this method, the flat Ge layers can be directly formed on highly B-doped Si(001) substrates using our proposed sputter epitaxy method. The RTDs exhibit clear negative differential resistance effects in the static current-voltage (I-V) curves at room temperature. The quantized energy level estimation suggests that resonance peaks that appeared in the I-V curves are attributed to hole tunneling through the first heavy- and light-hole energy levels.
