Atomic layers of MoS 2 have been used as a phototransistor and ultrasensitive detectors.
2.
The first frame is my ( admittedly poor ) understanding of a phototransistor's response time.
3.
What happens when the duration of the input is shorter than the phototransistor's response time?
4.
Please see this drawingThe first frame is my ( admittedly poor ) understanding of a phototransistor's response time.
5.
My question is, what happens when the duration of the input is shorter than the phototransistor's response time?
6.
Opto-isolators use an LED combined with a photodiode or phototransistor to provide a signal path with electrical isolation between two circuits.
7.
An infrared light source is transmitted through or reflected off the tissue, detected by a phototransistor, and quantified in arbitrary units.
8.
Within the patent they described a phototransistor chopper consisting of an LED optically coupled with a dual emitter, photosensitive, silicon transistor.
9.
In contrast to the photodiode and phototransistor, the photoresistor can operate in both the AC and DC circuits and have a voltage of several hundred volts across it.
