Electron tunneling lifetime of a quasibound state in a double-barrier resonant tunneling structure

Journal Article


Abstract


  • The level width of a quasibound state due to electron tunneling in a double-barrier resonant tunneling structure in an external electric field is investigated. The result for the width rests on the S-matrix resonant tunneling formalism. The inverse lifetime obtained in this manner is free of small parameter expansion and is exactly the width at the half-maximum of the resonant tunneling rate. It is found that for a system exhibiting current bistability, the level broadening of a quasibound state is not a monotonic function of the applied bias and has a minimum at some intermediate field strength.
