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 […]

Once A Performance Barrier, Material Quirk Could Improve Telecommunications
Researchers who study and manipulate the behavior of materials at the atomic level have discovered a way to make a thin material that enhances the flow of microwave energy. The advance, which could improve telecommunications, sheds new light on structural traits, generally viewed as static and a hindrance, that, when made to be dynamic, are […]
Terahertz Technology Creates New Insight Into How Semiconductor Lasers Work
Pioneering engineers working with terahertz frequency technology have been researching how individual frequencies are selected when a laser is turned on, and how quickly the selection is made. The development of specific terahertz equipment has allowed them to investigate this process for the first time. Their results, published in Nature Communications, will underpin the future development […]
Printed Electronics Breakthrough Could Lead To Flexible Electronics Revolution
A new form of electronics manufacturing which embeds silicon nanowires into flexible surfaces could lead to radical new forms of bendable electronics, scientists say. In a new paper published today in the journal Microsystems and Nanoengineering, engineers from the University of Glasgow describe how they have for the first time been able to affordably ‘print’ high-mobility […]
