Abstract
A macromolecular system embedded in a semiconductor microelectronic device is considered as a biomolecular nano- or micro-sized domain that performs the functions of converting acoustic and electromagnetic signals. The issues of the choice of substances, the dynamic and structural-functional state of the domain, as well as the physical foundations of its interaction with matrix elements are discussed. The process of excitation of forced vibrations in amino acid molecules (for example, glycine, tryptophan, diphenyl-L-alanine) under the influence of short (10–100 ps) packets of electrical signals in the IR range with a frequency in the range of 1–125 THz was studied by the method of supercomputer nonequilibrium modeling of molecular dynamics. The acoustoelectric interpretation of oscillation generation was carried out using a unified equivalent circuit of the peptide group. Examples of developed prototypes of heterogeneous devices are given. It is concluded that embedded biomolecular domains, presented as a multifunctional element base, are promising for signal conversion in hybrid microelectronics.
