Light drives the migration of charge carriers (electrons and holes) at the juncture between semiconductors with mismatched crystal lattices. These heterostructures hold promise for advancing optoelectronics and exploring new physics.

Epitaxy, or growing crystalline film layers that are templated by a crystalline substrate, is a mainstay of manufacturing transistors and semiconductors. If the material in one deposited layer is the same as the material in the next layer, it can be energetically fav...

Four Department of Energy national laboratories are joining Oak Ridge National Laboratory to expand an online crowdsourcing community for building technologies called JUMP, which bridges the gap between cutting-edge ideas and the marketplace. Joining ORNL in JUMP...

As part of the Bioenergy Study Tour hosted by the Department of Energy’s Bioenergy Technologies Office and Oak Ridge National Laboratory, participants will visit switchgrass fields and facilities in East Tennessee.

Researchers and others interested in establishing a sustainable bioeconomy in the U.S. are taking part in a five-day study tour led by the Department of Energy’s Oak Ridge National Laboratory. Approximately 70 attendees from DOE and its national laboratories, the ...

This rendering illustrates the excitation of a spin liquid on a honeycomb lattice using neutrons.

Researchers at the Department of Energy’s Oak Ridge National Laboratory used neutrons to uncover novel behavior in materials that holds promise for quantum computing. The findings, published in Nature Materials, provide evidence for long-sought phenomena in a two-dim...

Oak Ridge National Laboratory scientists combined imaging techniques to measure crystallization kinetics of perovskite films following exposure to a mixed halide vapor.

Researchers at the Department of Energy’s Oak Ridge National Laboratory have found a potential path to further improve solar cell efficiency by understanding the competition among halogen atoms during the synthesis of sunlight-absorbing crystals. 

In unbound calyx[4]pyrrole, two pyrrole “petals” are flipped up and two, down.

Atomic charges in chemical solutions are like Switzerland—they strive for neutrality. The tendency to balance charges drives dynamics when charged atoms or molecules, called ions, are present in solutions. Recently, researchers at the Department of Energy’s Oak Ridge National Laborat...

Red trillium is among the spring wildflowers found on the Oak Ridge Reservation.
Four more nature walks are planned this spring on the Department of Energy’s Oak Ridge Reservation beginning with a wildflower walk at 1:30 p.m. Sunday, April 10. Participants will see many native spring wildflowers in the woods along the bluffs of Watts Bar Lake...

Lipid molecules have split personalities—one part loves water, whereas the other avoids it at all costs. Lipids make up cell membranes, the frontline defense in preventing cellular access to bacterial and viral invaders. Many researchers believe that the membrane is not just a scaf...
