WAVE-FUNCTION MIXTURE AND COMPOSITION FOR HYBRIDIZED ZEEMAN STATES OFP IN SI

We report the experimental determination of the wave-function mixture and composition for hybridized Zeeman states of P in Si and give a rel ated theoretical discussion. The intensity evolution of the Zeeman tra nsitions near the anticrossing region for the isolated P donors in hig hly pure Si has been measured quantitatively by means of high-sensitiv ity and high-resolution photothermal ionization spectroscopy. The wave -function compositions and their evolutions with magnetic field for th e hybridized Zeeman states of bounded electrons of impurities have bee n deduced from the measurement. A variational calculation in the frame work of the effective-mass approach has been performed to estimate the oretically the wave-function compositions, and a comparison has been m ade between the theoretical results and experimental ones.
