Isotope - Based Material Science

  title={Isotope - Based Material Science},
  author={G. P. Plekhanov},
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 - diffu- sion in bulk material as well as isotope…

Application of Isotopic Materials Science in Bulk and Low-Dimensional Structures

This chapter reviews the application of isotopic materials science in different fields of nanotechnology and nanoscience. The application of stable isotopes is very briefly described: in first step

Phonon States in Bulk and Low-Dimensional Structures

The accumulated voluminous theoretical and experimental data suggest that the isotope composition of a crystal lattice exerts some influence on the thermal, elastic, and vibrational properties of

Preparation of Isotopically Enriched Polycrystalline Germanium via Monogermane Pyrolysis

Abstract— High-purity isotopically enriched germanium has been prepared by a hydride method, and the main factors capable of reducing the germanium yield in the monogermane pyrolysis process have

A roadmap for electronic grade 2D materials

Since their modern debut in 2004, 2-dimensional (2D) materials continue to exhibit scientific and industrial promise, providing a broad materials platform for scientific investigation, and

A Roadmap for Electronic Grade 2-Dimensional Materials

Two dimensional (2D) materials continue to hold great promise for future electronics, due to their atomic-scale thicknesses and wide range of tunable properties. However, commercial efforts in this



Isotope effects on the optical spectra of semiconductors

Since the end of the cold war, macroscopic amounts of separated stable isotopes of most elements have been available ``off the shelf'' at affordable prices. Using these materials, single crystals of

Wannier-Mott excitons in isotope-disordered crystals

Most of the physical properties of a solid depend to a greater or lesser degree on its isotopic composition. Scientific interest, technological promise and increased availability of highly enriched

Isotopically engineered semiconductors

Scientific interest, technological promise, and increased availability of highly enriched isotopes have led to a sharp rise in the number of experimental and theoretical studies with isotopically

Fundamentals and Applications of Isotope Effect in Modern Technology

Different crystals (semiconductors and insulators) with varying isotopic composition have been recently grown. I discuss here the effect of isotopic mass and isotopic disorder on the properties

Applications of isotope effects in solids

This article reviews the current status of the employment of the isotope effect in solids. Diffusion, self-diffusion processes with different isotopes in pure materials and heterostructures (quantum

Isotopic effects in lattice dynamics

The large number of available stable isotopes and well developed isotope separation technology have enabled growing crystals of C, LiH, ZnO, CuCl, CuBr, Cu2O, CdS, ?-Sn, Ge, Si, etc. with a

Semiconducting and other major properties of gallium arsenide

This review provides numerical and graphical information about many (but by no means all) of the physical and electronic properties of GaAs that are useful to those engaged in experimental research
