Radiation detectors and methods of fabricating radiation detectors are provided. A method includes contacting at least a portion of the semiconductor material with a passivating agent. Post-processed positioning techniques are continuously applied to the stored position data to iteratively determine calibrated position locations to provide calibrated second trajectory segments in a real-time fashion. In the transmitting end, based on consistent degree of the received N TPC command data group and the encoded symbol, a corresponding power control mode is determined. The flow path includes a portion that is configured to communicate with a remote source of suction. The structure includes two devices connected by metal wires on a same wiring level.
