The ability to make atomic-level changes in the functional components of semiconductor switches, demonstrated by a team of Oak Ridge National Laboratory, North Carolina State University and University of Tennessee physicists, could lead to huge changes in the semiconductor industry. The results are reported in the June 13 issue of Science.
This image illustrates the concept of “Coulomb buffer,” the region between oxide (above) and silicon (below) in nanoswitches, that can be “tuned” through atomic-level manipulation for desirable semiconductor characteristics, an advance that benefits both researchers and manufacturers.
Semiconductor devices, the building blocks of computing chips that control everything from coffee makers to Mars landings, depend on microscopic solid-state transistors, tiny electronic on-off switches made of layers of metals, oxides and silicon. These switches stop and start the flow of electrons, and work themselves because of the microscopic interface between the oxide layer and the silicon layer, in the realm of individual atoms, where minute positive and negative charges determine semiconductor success or failure.
Until now, researchers – and the multibillion-dollar semiconductor industries they support – had to accept the limitations that each crucial interface contains.

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
