The electrical and optical characteristics of HPT are analyzed with different base thickness and compared as the base was scaled from 60 down to 20 nm. WebPNP phototransistors are current-operated devices that convert light into current when exposed to light. These devices are typically used in applications where current needs to be either stored or converted into voltage. PNP phototransistors have a higher resistance when in the dark, but this decreases as the intensity of light increases. mfg boats history
