Semiconductor materials play an important part in developing nanophotonic technologies. Semiconductors are used for generating controllable photons as well as for confining and exploiting them for ...

In a semiconductor, electrons can be excited by absorbing laser light. Advances in the past decade have enabled measuring this fundamental physical mechanism on timescales below a femtosecond (10-15 s ...

The word semiconductor is comprised of two words, semi (not complete) and conductor (something that can conduct electricity). Electricity is present everywhere, like in home appliances where current ...

Electronics and Telecommunications Research Institute (ETRI) of Korea and its research team have successfully developed core material and device process technologies of gallium oxide (Ga2O3) power ...

A semiconductor is a material or device that only conducts electricity under certain conditions. Some elements in the periodic table, such as carbon, silicon, and germanium, are intrinsic ...

In recent years, the energy consumption in developed countries has been rather wasteful. Nearly two-thirds of the total energy is typically discarded into the environment as "waste heat," which ends ...

The thermal conductivity of boron arsenide can compete with diamond. Discover how this challenges theoretical limits and ...

Bandgap refers to a region of an element’s crystal’s electronic band structure through which electrons can’t pass. Also referred to as an energy gap, bandgap is a concept in solid-state physics and ...

Scientists demonstrate double charge carrier type switching of tin SnSe semiconductor by doping of antimony Sb. The SnSe carrier type switches from p-type to n-type, and re-switches to p-type as ...
