ABSTRACT
As is well - known isotopes of a given element have identical numbers of protons but differ in the number of neutrons making up their nuclei. Particularly, in crystalline solids, this difference in nuclear mass most directly affects vibrational phenomena, i.e. phonon frequencies and all phonon - related properties. These include exciton binding energy, electronic band gaps, lattice constant, local and crystalline vibrational modes, self - diffusion in bulk material as well as isotope superlattices (see, e.g. reviews [1, 2]). The experience of the past shows that throughout constant technology improvement electronics(optoelectroelectronics)has become more reliable, faster, more powerful, and less expensive by reducing the dimensions of integrated circuits. These advantages are the driver for the development of modern microelectronics. The long - term goal of this development will lead to nanoelectronics. Advancing to the nanoscale is not just a step toward miniaturization, but requires the introduction and consideration of many additional phenomena. at the nanoscale, most phenomena and processes are dominated by quantum physics and they exhibit unique behavior. Nanotechnology includes the integration of man - made nanostructures into large material components of system (see, e.g. [3, 4]). Nanoscience and nanotechnology are concerned with materials, structures and systems whose components exhibit novel and significantly modified physical, chemical properties due to the nanoscale sizes. New direction of nanosciene is isotopetronics, who is studied the more low - dimensional size, as a rule the sizes of the sample of isotopetronis compare to the atomic size. Over the last five decades the large number of experimental and theoretical studies of isotopetronics have created the new branch of material science, which is called the isotope - based material science. Isotopetronics may find applications in quantum computing, nanoscience and spintronics. This review contains a brief introduction to the isotope - based material science.
