WebNov 26, 2024 · Ultraviolet photocarrier radiometry (UV-PCR) was used for the characterization of thin-film (nanolayer) intrinsic hydrogenated amorphous silicon (i-a-Si:H) on c-Si. The small absorption depth (approximately 10 nm at 355 nm laser excitation) leads to strong influence of the nanolayer parameters on the propagation and recombination of … WebCarrier-Density Diffusion-Waves in Semiconductors and Metrology using Carrier and Thermal Waves.

WebOct 13, 2024 · Photocarrier radiometry (PCR) measured the carrier distribution of a p-type Si wafer at room temperature. Figure 1 shows PCR images taken at 5 kHz for two regions located at the central part of an S6 wafer. As can be seen, the PCR amplitude signal showed variations across the studied areas, indicating changes in the carrier distribution.
