Plasmon Satellites of Resonantly Tunnelling Holes
Hole resonant tunnelling is investigated in an asymmetric p-type RTD which exhibits intrinsic multistability on the first light-hole (LH1) resonant peak. This device exhibits two previously unseen satellite peaks just beyond the LH1 resonant peak. Both satellites are strongly dependent on temperature and quench above 18K. We have modeled the tunneling transitions in our devices and show that these features are due to plasmon-assisted resonant tunneling of holes.
