Transport through (Ga,Mn)As nanoislands: Coulomb blockade and temperature dependence of the conductance
Transport through (Ga,Mn)As nanoislands: Coulomb blockade and temperature dependence of the conductance
We report on magnetotransport measurements of nanoconstricted (Ga,Mn)As devices showing very large resistance changes that can be controlled by both an electric and a magnetic field. Based on the bias voltage and temperature dependent measurements down to the millikelvin range we compare the models currently used to describe transport through …
