What else can I help you with?
Explain the generation and recombination of electrons and holes in semiconductor?
Simply, the two fundamental laws are energy conservation and and momentum conservation.
What is the two parameter that minority carrier lifetime depend on?
The minority carrier lifetime primarily depends on two parameters: the concentration of impurities (dopants) in the semiconductor and the temperature of the material. Higher impurity concentrations can lead to increased recombination rates, thereby reducing the lifetime. Additionally, elevated temperatures typically enhance thermal energy, which can increase carrier recombination processes, further affecting the lifetime.
When was ON Semiconductor created?
ON Semiconductor was created in 1999.
When was Vitesse Semiconductor created?
Vitesse Semiconductor was created in 1984.
Is carbon is semiconductor?
Nothing has been found about the electrical conductivity of carbon compared to other conductors. It is not a semiconductor.
What is recombination and lifetime?
Recombination is the process by which electrons and holes combine in a semiconductor to generate light or heat. It plays a crucial role in determining the efficiency of devices such as solar cells and LEDs. Lifetime refers to the average time an electron or hole remains in the semiconductor before recombining; a longer lifetime indicates better efficiency in devices.

Simply, the two fundamental laws are energy conservation and and momentum conservation.
What is recombination center?
the point where in a semiconductor minority carrier is captured in a charged point defect and recombined with subsequently captured majority carrier.
What is the principle of semiconductor laser?
Semiconductor lasers are diodes which are electrically pumped. Recombination of electrons and holes created by the applied current introduces optical gain. Reflection from the ends of the crystal form an optical resonator, although the resonator can be external to the semiconductor in some designs.
Give some Examples of direct and indirect band gap semiconductors?
direct band gap-semiconductor in which the bottom of the conduction band and the top of the valence band occur at the momentum k=0;in the case of d.b.s. energy released during band-to-band electron recombination with a hole is converted primarily into radiation (radiant recombination); wavelength of emitted radiation is determined by the energy gap of semiconductor; examples of d.b.s. GaAs, InP, ZnS, ZnSs, CdS, CdSe etc. indirect bandgap semiconductor --semiconductor in which bottom of the conduction band does not occur at effective momentum k=0, i.e. is shifted with respect to the top of the valence band which occurs at k=0; energy released during electron recombination with a hole is converted primarily into phonon; e.g. Si, Ge, GaP, GaAsp ,Ge etc, .
What does GND Mean in the Semiconductor World?

What does recombination mean?
Somatic recombination is the method by which functional antibody genes are created. It involves the rearrangement of many gene segments that code for the heavy and light chain proteins of immunoglobulins, and it only occurs in lymphocytes.
What does O mean in CMOS?
Oxide as in Complimentary-Metal-Oxide-Semiconductor (CMOS)
What is inhereited variation with recombination and gene flow?
What is inertied variation with recombination .
