Power/Performance Bits: June 28


Making uniform wafers Scientists from the Korea Institute of Machinery & Materials (KIMM) and Nanyang Technological University Singapore (NTU Singapore) propose a technique that combines nanotransfer printing with metal-assisted chemical etching to improve wafer uniformity and increase yield. The researchers used a chemical-free nanotransfer printing technique that transfers gold nanost... » read more

Week In Review: Manufacturing, Test


Broadcom announced it will acquire cloud computing and virtualization company VMware for about $61 billion in cash and stock, and assume $8 billion in VMware net debt. If all goes as planned, the Broadcom Software Group will rebrand and operate as VMware. “The combined solutions will enable customers, including leaders in all industry verticals, greater choice and flexibility to build, run, m... » read more

Argonne & Univ. of Chicago: Using Quantum Computers to Simulate Quantum Materials


Research study titled "Simulating the electronic structure of spin defects on quantum computers," by Argonne National Laboratory and the University of Chicago. Abstract: "We present calculations of the ground and excited state energies of spin defects in solids carried out on a quantum computer, using a hybrid classical/quantum protocol. We focus on the negatively charged nitrogen vacancy c... » read more

Research Bits: May 17


Magnetic storage structures Researchers from The Ohio State University and Universidad Nacional Autonoma de Mexico investigated a new material that could potentially increase the capacity of magnetic storage devices. They identified manganese germanide, an unusual magnetic material in which the magnetism follows helices, similar to the structure of DNA. The structure gives rise to a number ... » read more

Fingerprinting quantum noise Scientists from the University of Chicago and Purdue University propose a different method of understanding the effect of noise in quantum computers. Instead of trying to measure it directly, they created a 'fingerprint' of how the noise impacts a program run on the computer. “We wondered if there was a way to work with the noise, instead of against it,” sai... » read more

Nanoporous Dielectric Resistive Memories Using Sequential Infiltration Synthesis


Abstract "Resistance switching in metal–insulator–metal structures has been extensively studied in recent years for use as synaptic elements for neuromorphic computing and as nonvolatile memory elements. However, high switching power requirements, device variabilities, and considerable trade-offs between low operating voltages, high on/off ratios, and low leakage have limited their utility... » read more

Power/Performance Bits: Oct. 12


More stable quantum states Researchers at the University of Chicago found a way to make quantum systems retain coherency 10,000 times longer. The fragile nature of quantum states remains a challenge for developing practical applications of quantum computing, as they can be easily disrupted by background noise coming from vibrations, temperature changes or stray electromagnetic fields. Ap... » read more

Power/Performance Bits: Sept. 22


Drawing sensors on skin Researchers from the University of Houston and University of Chicago created an ink pen that can draw multifunctional sensors and circuits directly on skin. These "drawn-on-skin electronics" aim to provide more precise health data, free of the artifacts that are associated with wearable devices and flexible electronic patches. Caused when the sensor doesn't move prec... » read more
