摘要
A method has been developed to measure strain in ultra-thin (<50 Angstrom) buried films. The presence of the film leads to a step in the yield of the host crystal in a channeled RES spectrum for off-normal crystal axes. The size of this step depends on the Aux distributions in the channel, which in turn depend on the angle psi between the incoming beam and the crystal axis. Two maxima in the step size appear as a function of the angle psi. Monte Carlo (MC) simulations have been used to interpret the experiments. (C) 2000 Elsevier Science B.V. All rights reserved.
