Теорія електронної провідності відкритої циліндричної двобар'єрної симетричної резонансно-тунельної структури у моделі прямокутних та δ-подібних потенціальних бар'єрів

摘要

The theory of resonance energies (RE) and resonance widths (RW) of electron quasi stationary states (QSS) and electronic conductivity is developed in an open two barrier resonance tunel structure (RTS) of cylindrical shape. The whole Schrodinger equation is solved within the framework of two models effective masses and rectangular potential wells and barriers model and effective masses and rectangular potential wells and δ- like barriers model . Within both approaches the electron interaction with electro magnetic field is taken into account in the approximation of weak signal For the nanosystem In₀,₅₃Ga₀,₄₇As/In₀,₅₂Al₀,₄₈As, the calculations of spectral parameters are performed the dependences of conductivity on mono energetic electron beam falling at RTS energy and electromagnetic field energy emitted and absorbed by the system are obtained and analysed For the first time there is established a direct relation between experimentally measured parameters of conductivity and resonance widths of electron QSS in open RTS.
