Next-generation devices made with new “peel and stack” method may include electronic chips worn on the skin.  more

Researchers quickly harvest 2-D materials, bringing them closer to commercialization

October 11, 2018

Since the 2003 discovery of the single-atom-thick carbon material known as graphene, there has been significant interest in other types of 2-D materials as well. These materials could be stacked together like Lego bricks to form a range of devices with different functions, including…  more

Transparent Graphene

September 13, 2018

The vast majority of computing devices today are made from silicon, the second most abundant element on Earth, after oxygen. Silicon can be found in various forms in rocks, clay, sand, and soil. And while it is not the best semiconducting material that exists on the planet, it is by far the most…  more

Jeehwan Kim is developing software that links to hardware to create intelligent devices

June 29, 2018

Kim and others are developing new software that links up to hardware to create intelligent devices. Currently, most neural networks have been developed using the Von Neumann computing method and have been software-based. Kim has been taking a different approach and been using neuromorphic…  more

Engineers design artificial synapse for “brain-on-a-chip” hardware

January 23, 2018

Researchers in the emerging field of “neuromorphic computing” have attempted to design computer chips that work like the human brain. Instead of carrying out computations based on binary, on/off signaling, like digital chips do today, the elements of a “brain on a chip” would work in an analog…  more

Not stuck on silicon

April 19, 2017

A new technique developed by Jeehwan Kim and a team of researchers may vastly reduce the overall cost of wafer technology and enable devices made from more exotic, higher-performing semiconductor materials than conventional silicon. The new method, reported today in Nature, uses graphene…  more

Researchers “iron out” graphene’s wrinkles

April 5, 2017

Jeehwan Kim has a PNAS paper in which he confirms that a technique he previously developed does indeed create single domain graphene, meaning graphene that uniformly conducts electrons.…  more
