Electron orbitals provide information on the whereabouts of the electrons in atoms and molecules. Scientists have now succeeded in experimentally recording these structures in all three dimensions. They achieved this by further developing a method they had already applied two years ago to make these orbitals visible in two dimensions.
Researchers have assembled model microscopic system to demonstrate the transmission of torque in the presence of thermal fluctuations - necessary for the creation of a tiny 'clutch' operating at the nanoscale.
Researchers have introduced a new class of light-emitting quantum dots with tunable and equalized fluorescence brightness across a broad range of colors. This results in more accurate measurements of molecules in diseased tissue and improved quantitative imaging capabilities.
To understand how a TMD semiconductor behaves inside a device, researchers investigated the effects of sub-monolayer deposition of alkali atoms at the surface of the semiconductor tungsten selenide. These deposited atoms mimics the electric field effects that a semiconductor would experience inside a transistor, while allowing researchers to directly analyse the electronic structure by a state of the art spectroscopic technique.
Researchers develop elegant process for coating fragile perovskite layers with graphene for the first time. Subsequent measurements show that the graphene layer is an ideal front contact in several respects.
The choice for energy-efficient technologies is not a matter of price choice but it is slowly turning into a matter of heat. A recent work suggests devices fabricated directly on Silicon with magnetic tunnel junctions governed by electric pulses, which means without current and minimizing the problem of overheating.
Scientists have developed a technology for contactless deposition of liquids at nanoscale. In doing so, they make use of an electric field. Their technology will lead to new 3D-applications and can be of great value to, for example, cell research, nano-lithography and printable electronics.
New research shows that applying a moderate in-plane magnetic field increases spin lifetime of electrons in graphene. The results of this work have profound implications for graphene's use as post-CMOS platform in spintronics, and make an important contribution to the understanding of physics of 2D materials.
Researchers for the first time have applied a modern theory of heat transport in experiments with semiconductors used in computers and lasers, with implications for the design of devices that convert waste heat into electricity and the control of overheating in miniaturized and high-speed electronic components.
