Energy dependence of zero-degree focusing of channeled ions
(Radiation Effects and Defects in Solids, 1997)
We analyze here the energy dependence of the effect of zero-degree focusing of Ne10+ ions transmitted through the [100] channels of a Si crystal. The thickness of the crystal is 1 mu m and the ion energy is varied from 1.0 ...
Energy loss of ions channeled in a thin crystal
(Radiation Effects and Defects in Solids, 1997)
The energy loss distributions of Ne10+ ions channeled in a [100] Si thin crystal are considered. The thickness of the crystal is 500 nm (921 atomic layers), while the ion energy is varied from 1 to 35 MeV per nucleon. The ...
The X9 catastrophe as the organizing center of crystal rainbows
(Physics Letters A, 1993)
The crystal rainbow effect is modeled by the catastrophe theory. It is shown that the 4X9 catastrophe can be treated as the organizing center of the crystal rainbows in the cases of square, rectangular, centered rectangular ...
Optimization of nonlinear optical rectification in quantum wells using the supersymmetric quantum mechanics
(Optics Communications, 1997)
A systematic procedure is proposed for optimized design of semiconductor quantum well structures that provide maximal values of the resonant optical rectification coefficient. It relies on employing supersymmetric quantum ...
