Semiconductor electronic devices can be made of either inorganic crystals, formed by the strong bonding of atoms and ions, or organic crystals, which demonstrate weaker bonds held together by van der Waals forces (weak electric forces of attraction between neutral atoms or molecules that do not share a chemical bond).
Amorphous oxide semiconductors (AOS) are a promising option for the next generation of display technologies due to their low costs and high electron (charge carrier) mobility.
Semiconductors are moving away from rigid substrates, which are cut or formed into thin discs or wafers, to more flexible plastic material and even paper thanks to new material and fabrication discoveries.
Photon upconversion (UC) is a process in which a material increases the energy of incident photons, resulting in the emission of photons with higher energies. The potential applications of UC include the recovery of wasted low-energy photons in photovoltaics and photocatalysis.
A new process has resulted in layered materials that can upgrade the efficiency levels of lasers and LEDs.
A mask aligner is a precision machine tool used in the semiconductor manufacturing process to transfer a pattern onto a wafer or substrate; these patterns are micro and nano in scale.
The application of Internet of Things has sparked intense interest of photodetectors as they are widely used in sensing, detection, data transport and processing.
In semiconductor device applications, there is an increasing demand for semiconductors with very high carrier concentrations.
Bandgap engineering can improve the performance of optoelectronic devices that aim to harness the energy of "hot" electrons, research from KAUST shows.
At the Samueli School of Engineering from the University of California Los Angeles (UCLA), electrical engineers have come up with a highly efficient method of converting light from one wavelength to another.
