Atomic and Molecular Beams Control in Molecular Beam Epitaxy

Nano- i Mikrosistemnaya Tehnika, 2021
Rapid development of molecular beam epitaxy (MBE) in recent decades has led to the emergence of a variety of technological installations, as well as electronic and optical diagnostics of growing layers, as well as atomic and molecular beams. Known methods for monitoring atomic and molecular beams in MBE installations-mass spectrometric and luminescent -

Molecular-Beam Epitaxy

AT&T Technical Journal, 1980
Molecular beam epitaxy is an ultrahigh vacuum technique for growing very thin epitaxial layers of semiconductor crystals. Because it is inherently a slow growth process, extreme dimensional control over both major compositional variations and impurity incorporation can be achieved.

Molecular beam epitaxy: An overview

2011
Molecular beam epitaxy (MBE) is an epitaxial technology suited for the preparation of advanced structures with composition and doping profiles controlled on a nanometer scale. The MBE growth mechanisms of both lowly (

A micromechanical detector for molecular beams

Review of Scientific Instruments, 1999
We demonstrate the detection of a molecular beam by means of a micromechanical momentum transfer detector operated in vibrational resonance. With a sensitive surface area of 0.5×0.3 mm2 the small paddle allows us to detect a beam with 6.5×107 He atoms hitting the surface per second.

MOLECULAR BEAM STUDIES OF FULLERENES

Carbon, 1992
Abstract A number of molecular beam experiments with the fullerenes are described. Such experiments allow a detailed probing of the interactions between fullerenes and other species and among the fullerenes themselves. Emphasis is placed on work involving photophysics and collisional interactions of the fullerenes.

Molecular beam probing of electron beams

IEEE Transactions on Electron Devices, 1979
Empirical electron-beam characterization by molecular beam probing has been applied to the interaction space of a gridded Injected Beam Crossed-Field Amplifier (IBCFA) and a nongridded M-Backward Wave Oscillator. A small gas stream, preferably helium or argon, is injected through a capillary into the electron beam.

SUPERSONIC MOLECULAR BEAMS: II. THEORY OF THE FORMATION OF SUPERSONIC MOLECULAR BEAMS

Canadian Journal of Chemistry, 1965
Supersonic molecular beams may be isolated from gas which has been allowed to expand through a nozzle. This paper concerns the kinetic theory of the isolation of such beams, taking into account the effect of collisions in the region between the skimmer and the collimator. These collisions turn out to be important.
