摘要:
Employing p+-ZnTe/ZnSe quantum wells whose sub-bands are aligned in energy so that resonant tunnelling of holes can occur through the multiquantum well region, nonalloyed ohmic contacts to p-type ZnSe have been realised. A specific contact resistance as low as 5.0 x 10(-2) OMEGA cm2 has been achieved for N-doped ZnSe with a hole concentration of 7.0 x 10(16) cm-3.
