Giant Fano Resonance of Infrared Photoconductivity in Ge:Te

We study Fano resonances between the conduction band and 1s(T2) donor levels with LO phonons in Te-doped Ge. The structures are explained by Fano resonance of LO phonon associated excited states of the donor with the conduction band. Interference due to an ionized impurity is responsible for the bro...

Description
Summary:We study Fano resonances between the conduction band and 1s(T2) donor levels with LO phonons in Te-doped Ge. The structures are explained by Fano resonance of LO phonon associated excited states of the donor with the conduction band. Interference due to an ionized impurity is responsible for the broad structure.
