Researchers from Graduate School of Bio-Applications and Systems Engineering at Tokyo University of Agriculture and Technology (TUAT) have sped up the movement of electrons in organic semiconductor films by two to three orders of magnitude. The speedier electronics could lead to improved solar power and transistor use across the world, according to the scientists. They […]

Novel Topological Insulator
Topological insulators are materials with very special properties. They conduct electricity or light particles on their surface or edges only but not on the inside. This unusual behaviour could eventually lead to technical innovations which is why topological insulators have been the subject of intense global research for several years. Physicists of Julius-Maximilians-Universität Würzburg (JMU) […]
Forcing a Metal To Be a Superconductor via Rapid Chilling
A team of researchers with the RIKEN Center for Emergent Matter Science and The University of Tokyo, both in Japan, has found a way to force a metal to be a superconductor by cooling it very quickly. In their paper published on the open access site, Science Advances, the group describes their process and how […]
Part-Organic Invention Can Be Used in Bendable Mobile Phones
Engineers at ANU have invented a semiconductor with organic and inorganic materials that can convert electricity into light very efficiently, and it is thin and flexible enough to help make devices such as mobile phones bendable. The invention also opens the door to a new generation of high-performance electronic devices made with organic materials that will be […]
Modular Angle Encoders for Semiconductor Measurement and Metrology
HEIDENHAIN announces a new series of angle encoders called the ERP 1000 with the design criteria of exceptionally high resolution, high speed, and high contamination resistance. These new unique encoders are particularly useful for highly accurate measurement and positioning applications within semiconductor and metrology equipment. Consisting of a glass disk bonded to a hub and a […]
‘Spacesuits’ Protect Microbes Destined to Live in Space
Just as spacesuits help astronauts survive in inhospitable environments, newly developed “spacesuits” for bacteria allow them to survive in environments that would otherwise kill them. University of California, Berkeley, chemists developed the protective suits to extend the bacteria’s lifespan in a unique system that pairs live bacteria with light-absorbing semiconductors in order to capture carbon […]
Cannibalistic Materials Feed on Themselves to Grow New Nanostructures
Scientists at the Department of Energy’s Oak Ridge National Laboratory induced a two-dimensional material to cannibalize itself for atomic “building blocks” from which stable structures formed. The findings, reported in Nature Communications, provide insights that may improve design of 2D materials for fast-charging energy-storage and electronic devices. “Under our experimental conditions, titanium and carbon atoms can […]
This Transistor Could Give Electric Vehicles a Power Boost
Electronic transistors made of gallium oxide—these components could increase the energy output and improve the design of electric vehicles, solar power, and other forms of renewable energy. Researchers at the University at Buffalo (UB) have recently made strides in this area, creating a gallium oxide-based, metal-oxide-semiconductor field-effect transistor (MOSFET) totaling 5 micrometers wide (a sheet of […]
Levitating 2-D Semiconductors For Better Performance
Atomically thin 2-D semiconductors have been drawing attention for their superior physical properties over silicon semiconductors; nevertheless, they are not the most appealing materials due to their structural instability and costly manufacturing process. To shed some light on these limitations, a KAIST research team suspended a 2-D semiconductor on a dome-shaped nanostructure to produce a […]
Nano-Imaging Of Intersubband Transitions In Few-Layer 2-D Materials
Semiconducting heterostructures have been key to the development of electronics and opto-electronics. Many applications in the infrared and terahertz frequency range exploit transitions, called intersubband transitions, between quantized states in semiconductor quantum wells. These intraband transitions exhibit very large oscillator strengths, close to unity. Their discovery in III-V semiconductor heterostructures depicted a huge impact within […]
