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.
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 ...
A semiconductor device is an electronic component that relies on the electronic properties of a semiconductor material ... which became known as surface physics, to ...
In electronics and semiconductor physics, the law of mass action relates the concentrations of free electrons and electron holes under thermal equilibrium.It states that, under thermal equilibrium, the product of the free electron concentration and the free hole concentration is equal to a constant square of intrinsic carrier concentration .
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).
µ is the total chemical potential of electrons, or Fermi level (in semiconductor physics, this quantity is more often denoted E F). The Fermi level of a solid is directly related to the voltage on that solid, as measured with a voltmeter. Conventionally, in band structure plots the Fermi level is taken to be the zero of energy (an arbitrary ...
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 ...
