IEEE Spectrum highlights Sanghamitra Neogi's atomic AI research

July 6, 2021

Physicists love recreating the world in software. A simulation lets you explore many versions of reality to find patterns or to test possibilities. But if you want one that’s realistic down to individual atoms and electrons, you run out of computing juice pretty quickly. Machine-learning models can approximate detailed simulations,...

AI may soon predict how electronics fail

June 24, 2021

Think of them as master Lego builders, only at an atomic scale. Engineers at CU Boulder have taken a major step forward in combing advanced computer simulations with artificial intelligence to try to predict how electronics, like the transistors in your cell phone, will fail. The new research was led...

Nanostructure research reveals new ways to direct heat flow in tech devices

Jan. 5, 2021

New findings from CU Boulder researchers in Physical Review Applied show that nanoscale structures on the surfaces of silicon membranes can significantly change the way that heat travels through the bulk of the membrane. This work could make existing devices that operate through silicon and other semiconductors – like cell...

Developing phononic neuromorphic materials to make computers that think like the human brain

Sept. 23, 2019

Sanghamitra Neogi is part of a team seeking nothing less than a revolutionary leap forward in computing technology by making computers work more like the human brain. The National Science Foundation thinks they may be onto something and has awarded a two-year, $1.7 million "Ideas Lab" grant to further the research. Investigations into...

Seminar: Phonon and Electron Transport in Nanostructured Semiconductors: A Perspective for Aerospace Applications - Oct. 10

Oct. 5, 2018

Sanghamitra Neogi - Assistant Professor, Smead Aerospace Wed. Oct. 10, 2018 | DLC | 12:00 pm Download Flyer Abstract: Heat conduction in macroscopic continuum media is well described by classical physics. However, with continued miniaturization of electronic transistors, sensors and actuators, device dimensions are now reaching the nanoscale. Classical framework...

DARPA Grant for Nano-Sized Research Could Lead to Big Changes

Nov. 8, 2016

Dead cell phones are the problem of the 21st-century. Walk into any coffee shop or airport and every outlet in sight will be plugged with chargers. However, what if you never had to worry about charging your phone again, because your charger was your own body heat. It's a future...
