Single dopants in semiconductors.
The sensitive dependence of a semiconductor's electronic, optical and magnetic properties on dopants has provided an extensive range of tunable phenomena to explore and apply to devices. Recently it has become possible to move past the tunable properties of an ensemble of dopants to identify the effects of a solitary dopant on commercial device performance as well as locally on the fundamental ...
متن کاملSingle dopants in semiconductors.
The controlled introduction of dopant atoms to semiconducting host materials is the corner stone of electronic device fabrication. Dopant atoms provide a means to modulate the electronic, optical, and magnetic properties of semiconductors [1], and it is now possible to control dopant profiles with true atomic-scale precision in the laboratory [2]. Moreover, industrial fabrication methods are no...
متن کاملInfluence of ionizing dopants on charge transport in organic semiconductors.
Ionizing chemical dopants are widely used in organic semiconductors to enhance the charge transport properties by increasing the number of mobile charge carriers. However, together with mobile charges, chemical doping produces anion-cation pairs in the organic matrix. In this work we use experimental and computational analysis to study the influence of these ionic species on the charge transpor...
متن کاملDependence of Electron Mobility on Dopants in Heavily Doped Semiconductors
At high doping concentrations the transport of conduction electrons is predominantly determined by charged-impurity scattering. Experiments have shown that the electron mobility is different for various dopants. It was found that the mobility in As-doped Si was significantly lower than that in P-doped Si for doping concentrations higher than 1018 cm-3 . Also, the mobility of minority electrons ...
