Semiconductors

Some organic materials might be able to be utilised similarly to silicon semiconductors in optoelectronics. Whether in solar cells, light-emitting diodes, or in transistors – what is important is the band gap, i.e. the difference in energy level between electrons in the valence band (bound state) and the conduction band (mobile state). Charge carriers can […]

By adding one more layer of atoms to already infinitesimally small semiconductors, a next-level generation of electrical devices becomes possible. This work to build better and faster electronics is well underway, but little was known about how to test the ingredients of these devices to ensure performance. Now, researchers from the Nagoya Institute of Technology […]

Rapid advancements in the Internet of Things (IoT) are accelerating its adoption across the industrial realm. While the number of active IoT devices as of 2018 was about 7 billion, it’s estimated to reach 22 billion by 2025. These will encompass all sorts of devices used across sectors like healthcare, retail, transportation, wearables, and much […]

Semiconductors, which are the basic building blocks of transistors, microprocessors, lasers, and LEDs, have driven advances in computing, memory, communications, and lighting technologies since the mid-20th century. Recently discovered two-dimensional materials, which feature many superlative properties, have the potential to advance these technologies, but creating 2-D devices with both good electrical contacts and stable performance […]

Collaborating scientists at the U.S. Department of Energy’s Ames Laboratory, Brookhaven National Laboratory, and Princeton University have discovered a new layered ferromagnetic semiconductor, a rare type of material that holds great promise for next-generation electronic technologies. As the name implies, semiconductors are the Goldilocks of electrically conductive materials– not a metal, and not an insulator, […]

R2-D2 and C-3PO, the robots in the popular movie Star Wars, gave us a glimpse of the artificial intelligence (AI) robots of the future. While some prefer the term “deep learning” over AI, both names pretty much mean the same thing. In recent years, AI robots have become a reality. Sophia, a female robot built […]

Light emitting diodes or LEDs are only able to produce light of a certain colour. However, white light can be created using different colour mixing processes. “In a white LED, red and yellow-green phosphors are excited by the light from a blue diode. The particles emit light in the red and green range, and in […]

A physical effect known as superinjection underlies modern light-emitting diodes (LEDs) and lasers. For decades this effect was believed to occur only in semiconductor heterostructures — that is, structures composed of two or more semiconductor materials. Researchers from the Moscow Institute of Physics and Technology have found superinjection to be possible in homostructures, which are […]
