K. Kadas et S. Kugler, IMPURITY LEVELS IN PHOSPHORUS-DOPED AND BORON-DOPED AMORPHOUS-SILICON, Philosophical magazine. B. Physics of condensed matter. Statistical mechanics, electronic, optical and magnetic, 76(3), 1997, pp. 281-285
The AMI semiempirical quantum-chemical method has been used to investi
gate phosphorus and boron-doped amorphous silicon. A simple relationsh
ip for the determination of midgap energy levels is proposed for subst
itutionally doped amorphous silicon as a function of distances between
dopants.
