Investigation of structural, energy state and kinetic characteristics of RNiSb semiconductor (R = Gd, Lu)
Journal Title: Фізика і хімія твердого тіла - Year 2016, Vol 17, Issue 1
Abstract
The features of structural, energy state and kinetic characteristics of the p-GdNiSb and p-LuNiSb semiconductors were investigated in the temperature range T = 4.2-400 K. As example, in p-LuNiSb, the generating of structural acceptor defects as a result of the emergence of vacancies upto 6 % in the 4c positions of Ni (3d84s2) atoms and partial, up to 1.35 %, substitution of Ni (4c) atoms by Lu (5d16s2) ones was shown.
