Essay

Thesis is devoted to the development of the theory of functioning and optimization of the parameters of the active element of the broadband nano photodetector of the far infrared range with a new potential profile. As well as the creation, based on the Davydov’s model, of the theory of renormalization of the spectra of a multilevel quasiparticle interacting with single-mode phonons and a single-level quasiparticle interacting with multilevel phonons, taking into account multiphonon processes in the studied multilayer nanostructures. boun
