Instabilities in crystal growth by atomic or molecular beams
Abstract When growing a crystal, a planar front is desired for most of the applications. This plane shape is often destroyed by instabilities of various types. In the case of growth from a condensed
Continuum models of crystal growth from atomic beams with and without desorption
Continuum equations appropriate to describe crystal growth from atom beams are derived in various cases. When desorption is important, the growth is described on very long lengthscales by the
Two-level systems in a spin-glass model. I. General formalism and two-dimensional model
A spin-glass model with two-dimensional, isotropic spins (XY model) is studied. The model exhibits two-level systems (TLS) which are related to the sense of rotation of the spin direction. The
Growth with Surface Diffusion
A simple growth model is investigated where particles are deposited onto a substrate randomly and subsequently relax into a position nearby where the binding is strongest. In space dimension d = 2
Insulating spin glasses
The possibility of obtaining spin glasses by addition of impurities in an antiferromagnetic insulator is examined. Dipolar interactions are briefly considered but the attention is focussed on
Spin glass with non-random interactions
Magnetic systems with competing ferromagnetic and antiferromagnetic inter- actions are investigated and a few exact results are obtained. The possibility of exact solutions comes from the fact that
Two-level systems in a spin-glass model: II. Three-dimensional model and effect of a magnetic field
For pt.I see ibid., vol.10, p.4793 (1977). The author studies a spin-glass model consisting of two-dimensional spins lying at the sites of a simple cubic lattice and interacting through
