The invention relates to a process for producing an electronic structure that includes a thin layer of strained semiconductor material from a donor wafer. The isolator includes a conically-shaped magneto-rheological elastomer component attached to opposing faces of a first and second mounting plate. Preferably, the all-optical regenerator device, the distortion compensator device, and the quality-of-signal monitoring device are disposed within a single module. This slurry may or may not also contain soft abrasive particles, which replace the hard abrasive particles of conventional slurries. The cargo is attached to the cargo end portion and is releasably held a selected projected length from the rail.
