Abstract
We have investigated the resonant tunnelling of electrons through X-valley related states in a single AlAs barrier with Si donor delta -doping. Under high hydrostatic pressure all the peaks observed in the differential conduc tance-voltage (sigma- V) characteristics shift with a pressure rate of -15 meV/kbar, which is expected for X-minima related electronic states.
