Thus, for all practically significant RTD designs (barrier width range up to 8–10 monolayers, well width up to 20 monolayers), the width of the resonant levels is about 0.01 meV and lower, while at the lowest operating temperatures (77 K), the thermal energy is 7 meV; The tunnel transparency coefficient and the local density of states depending on the energy in the vicinity of the resonant levels can be approximated by a function proportional to the Lorentz distribution function.
