摘要：
Diamagnetic shifts of p-type modulation-doped quantum wires are investigated, Both the heavy- and light-hole-like states are observable in the photoluminescence spectra by heavily doping holes above the light-hole-like state. This allows us the first measurement of the diamagnetic shifts of both the heavy- and light-hole-like states in quantum wires. The observed large diamagnetic shift coefficients are due to asymmetric distribution of the charge densities of an electron and holes in quantum wires.
