The Effect of Non-Equilibrium Acoustic Phonons on the Tunnel Current in GaAs/AlAs Superlattices
Non-Equilibrium Acoustic Phonons Tunnel Current GaAs/AlAs Superlattices
2010/4/16
We present the first study of the effect of ballistic acoustic phonons generated by a heated metal film on the tunnel current in GaAs/AlAs superlattices. The phonon-induced increase of the tunnel curr...
