Reverse bias usually refers to how a diode is used in a circuit. If a diode is reverse biased,the voltage at the cathode is higher than that at the anode. Therefore, no current will flow until the electric field is so high that the diode breaks down. What is the order of reverse cur...
One embodiment of the invention provides a semiconductor diode device including a first conductivity type region, a second conductivity type region, where the second conductivity type is different from the first conductivity type, an intrinsic region located between the first conductivity type region and...
These diode... R Kalibjian,K Mayeda - 《Solid State Electronics》 被引量: 31发表: 1971年 Defects and laser action in GaAs diodes Precipitates and diffusion-induced dislocations were found in the zinc-diffused region. All the properties of the material that enter into the expression for the ...
diode is intended in particular to a generatrix of the alternating current. < / p & gt; & lt; p & gt; it comprises an insulating element in the form of a disk - interposed between a tail, and a body. It is intended to be mounted on a rotating element, parallel to the axis of ...
The ionic current rectification (ICR) is a non-linear current-voltage response upon switching the polarity of the potential across nanopore which is similar to the I–V response in the semiconductor diode. The ICR phenomenon finds several potential applications in micro/nano-fluidics (e.g., Bio...
A photodiode in which a pn junction is formed between the doped region (DG) formed in the surface of a crystalline semiconductor substrate and a semiconductor layer (HS) deposited above said doped region. An additional doping (GD) is provided in the edge region of the doped zone, by means...
An analytical theory is given for the space-charge-limited (SCL) current of an electron diode in the presence of collisions. It extends the improved SCL current formula, which already takes into account the effect of nonzero electron injection velocitiesv0,by treating collisions within a simple ...
It can drive 2 DC motors directly with a drive current reaching 2A. The motor output is equipped with eight high-speed schottky diode as protection. This driver carries neat circuit layout and bonded components, in addition, the multi-layer design enables it to be plugged to Aduino directly....
aIts current is stabilized by an on-chip resistor with positive temperature coefficient. The voltage reference is produced by compensating the positive temperature coefficient of a resistor by the negative temperature coefficient of the diode connected PMOS transistor by driving the constant current of ...
