Melting transition of two-dimensional crystals
(1978) [Artigo de periódico]The solíd-liquíd phase transítíon (PT) in two-dímensional crystals is studied under the assumption that it ís driven by the díssocíation of elastic dípoles. It ís shown that thís PT ís of tirst-order and corresponds to a ... -
Metastable acceptor centers in boron implanted silicon
(1995) [Artigo de periódico]The evolution of the electrical activation with the annealing time in B1 implanted (5.0 31014 cm22, 50 keV! Si was studied as a function of the annealing temperature. Electrical activation yields of 15%–30% were observed ... -
Microscopic formulation of a lattice-defect model
(1979) [Artigo de periódico]A microscopic construction method of lattice defects which can be represented by dislocation configurations in simple-cubic lattices and for interaction by central forces is given. In contrast to standard theories, where ...
