Together with Alfred Y . Cho, Arthur pioneered molecular beam epitaxy at Bell Laboratories, where he published a paper in July 1968 that described construction of epitaxial gallium arsenide layers using molecular beam epitaxy.

Other advanced experimental facilities include an ESCA ( electron spectroscopy for chemical analysis ), HRTEM ( high resolution transmission electron microscope ), MBE ( molecular beam epitaxy ), cluster generator and nano material research facility.

Heterojunction manufacturing generally requires the use of molecular beam epitaxy ( MBE ) or chemical vapor deposition ( CVD ) technologies in order to precisely control the deposition thickness and create a cleanly lattice-matched abrupt interface.

They received the 1982 IEEE Morris N . Liebmann Memorial Award " for the development and application of molecular beam epitaxy technology, " and the 1982 James C . McGroddy Prize for New Materials from the American Physical Society.

InAlN is grown epitaxially by metalorganic chemical vapour deposition or molecular beam epitaxy in combination with other semiconductor materials such as gallium nitride, aluminium nitride and their associated alloys to produce semiconductor wafers, which are then used as the active component in semiconductor device manufacture.

The alternating layers of the two different semiconductors which form the quantum heterostructure may be grown on to a substrate using a variety of methods such as molecular beam epitaxy ( MBE ) or metalorganic vapour phase epitaxy ( MOVPE ), also known as metalorganic chemical vapor deposition ( MOCVD ).

Das Sarma also made important contributions to the classical statistical mechanics problem of dynamical growth of systems far from equilibrium where his work introduced the standard model for understanding the molecular beam epitaxy of thin film growth, both from a continuum field theory viewpoint in terms of the so-called Das Sarma-Tamborenea model.

As an experimental physicist Stern contributed to the discovery of spin quantization in the Stern Gerlach experiment with Walther Gerlach in February 1922 at the Physikalischer Verein in Frankfurt am Main; demonstration of the wave nature of atoms and molecules; measurement of atomic magnetic moments; discovery of the proton's magnetic moment; and development of the molecular ray method which is utilized for the technique of molecular beam epitaxy.
