Abstract: A method for improving CdZnTe-based gamma-ray detectors is presented. A CdZnTe detector/crystal is exposed to acoustic waves. After exposure to acoustic waves, the CdZnTe gamma-detector gains higher resistivity and exhibits better spectral resolution and greater sensitivity. Further, when a batch of detectors is made according to the method of the present invention, the properties of the crystals are more homogenous, allowing for cheaper and more standardized detectors.

Abstract: A method of efficiently extracting the pull-in parameters of an electrostatically activated actuator. The actuator is modeled as an elastic element. For each of a plurality of deformations of the elastic element, a corresponding voltage is calculated. The highest such voltage is the pull-in voltage of the actuator. The corresponding deformation is the pull-in deformation of the actuator. Each deformation is defined by fixing a displacement of one degree of freedom of the elastic body and calculating corresponding equilibrium displacements of all the other degrees of freedom without the application of any external mechanical forces to ensure equilibrium. The actuator is altered to optimize whichever pull-in parameter is relevant to the desired application of the actuator.
