Exemplary embodiments provide semiconductor nanowires and nanowire devicesapplications and methods for their formation. The screwing member includes a head portion with a plurality of tooth portions, the load plate includes a tongue portion with a fixing hole for the screwing member going through, a recess near the fixing hole and a block in the recess, during the process of screwing the screwing member, the tooth portions touch with the block for making a sound. The operating parameters comprising at least one of the voltage across the SPAD during an active period, the voltage across the SPAD during a quench period, the duration of the quench period and the temperature of the SPAD. A similar process is disclosed for making other building cover materials having rows of nail tabs coinciding with standard stud spacing.
