Research Bits: March 6


2D TMDs on silicon Engineers at MIT, University of Texas at Dallas, Institute for Basic Science, Sungkyunkwan University, Washington University in St. Louis, University of California at Riverside, ISAC Research, and Yonsei University found a way to grow 2D materials on industry-standard silicon wafers while preserving their crystalline form. Using a new “nonepitaxial, single-crystalline g... » read more

Research Bits: Nov. 1


Atomic-level rare earth manipulation Scientists from Ohio University, Argonne National Laboratory, and the University of Illinois at Chicago have rotated a single, charged rare earth molecule on a metal surface without changing the charge. The team used scanning tunneling microscopy (STM) system to rotate a positively charged Europium base molecule with negatively charged counterions as a p... » read more

Site-Specific Compositional Info from Periodic Nanostructures Obtained Using Rutherford Backscattering Spectrometry


A new technical paper titled "Quantification of area-selective deposition on nanometer-scale patterns using Rutherford backscattering spectrometry" was published by researchers at IMEC and KU Leuven. "We present a site-specific elemental analysis of nano-scale patterns whereby the data acquisition is based on Rutherford backscattering spectrometry (RBS). The analysis builds on probing a larg... » read more

Machine Learning-Based Optimization Of Chiral Photonic Nanostructures: Evolution- And Neural Network-Based Design


Chiral photonics opens new pathways to manipulate light-matter interactions and tailor the optical response of metasurfaces and -materials by nanostructuring nontrivial patterns. Chirality of matter, such as that of molecules, and light, which in the simplest case is given by the handedness of circular polarization, have attracted much attention for applications in chemistry, nanophotonics and ... » read more

Light-Emitting V-Pits: An Alternative Approach toward Luminescent Indium-Rich InGaN Quantum Dots


Abstract: "Realization of fully solid-state white light emitting devices requires high efficiency blue, green, and red emitters. However, challenges remain in boosting the low quantum efficiency of long wavelength group-III-nitride light emitters through conventional quantum well growth. Here, we demonstrate a new direct metal–organic chemical vapor deposition approach to grow In-rich InGa... » read more

Power/Performance Bits: June 13


Theoretical all-carbon circuits Engineers at the University of Texas at Dallas, the University of Illinois at Urbana-Champaign, the University of Central Florida, and Northwestern University designed a novel computing system made solely from carbon. "The concept brings together an assortment of existing nanoscale technologies and combines them in a new way," said Dr. Joseph S. Friedman, ass... » read more
