Abstract :
Our paper is a first step towards tunnelling spectroscopy of individual X-minimum-related shallow donors. We investigated I–V characteristics of submicrometer mesa structures made on GaAs/AlAs/GaAs wafers δ-doped with silicon in the middle of AlAs layer. At View the MathML source and magnetic field up to View the MathML source we resolved well-separated peaks attributed to resonant tunnelling via individual donors.
