The first practical application of semiconductors in electronics was the 1904 development of the cat's-whisker detector, a primitive semiconductor diode used in early radio receivers. Developments in quantum physics led in turn to the invention of the transistor in 1947 [ 7 ] and the integrated circuit in 1958.
These LEDs used much larger semiconductor die sizes to handle the large power inputs. Also, the semiconductor dies were mounted onto metal slugs to allow for greater heat dissipation from the LED die. One of the key advantages of LED-based lighting sources is high luminous efficacy. White LEDs quickly matched and overtook the efficacy of ...
A definition in semiconductor physics, carrier lifetime is defined as the average time it takes for a minority carrier to recombine.The process through which this is done is typically known as minority carrier recombination.
In solid-state physics of semiconductors, carrier generation and carrier recombination are processes by which mobile charge carriers (electrons and electron holes) are created and eliminated. Carrier generation and recombination processes are fundamental to the operation of many optoelectronic semiconductor devices , such as photodiodes , light ...
Stephan W. Koch has worked on multiple topics in the general field of semiconductor optics. Before the year 1988, the state-of-the-art description of semiconductor optics and lasers was mainly based on simplified rate-equation approaches which cannot describe the nonequilibrium quantum kinetics of Coulomb-coupled electrons and holes (electronic vacancies in valence band).
In semiconductor physics, the depletion region, also called depletion layer, depletion zone, junction region, space charge region, or space charge layer, is an insulating region within a conductive, doped semiconductor material where the mobile charge carriers have diffused away, or been forced away by an electric field. The only elements left ...
A semiconductor device is an electronic component that relies on the electronic properties of a semiconductor material ... which became known as surface physics, to ...
This is because quantum well devices require structures that are of high purity with few defects. Therefore, having great control over the growth of these heterostructures allows for the development of semiconductor devices that can have very fine-tuned properties. [4] Quantum wells and semiconductor physics has been a hot topic in physics ...
