Abstract
A special solid-phase epitaxy technique utilizing the surfactant B for the growth of crystalline Si-QWs on Ca F2 Si (111) enabled us to grow Ca F2 SiCa F2 double-barrier diodes exhibiting resonant tunneling effects from 77 K up to room temperature with peak voltages at 0.2 eV, which is very close to simple resonant tunneling model predictions. The peak voltages and currents were virtually independent of temperature. No trapping or hysteresis effects were found in the I-V characteristics which exhibited 2-7 orders of magnitude larger peak current densities than previously reported Ca F2 SiCa F2 RTDs.
