A total of 165 students will spend next summer learning, networking, and conducting scientific research at seven of the nation’s national laboratories via funding from the Department of Energy’s (DOE) Reaching a New Energy Sciences Workforce (RENEW) initiative.  

In 2D quantum materials, chiral edge states are 1D conducting channels in which electrons travel only in one direction and electron collisions are strongly suppressed. This means chiral channels act like resistance-free conductors. Researchers have created chiral edge states in atomically thin devices made of three graphene layers, paving the way for more efficient future electronics.

For the first time since X-rays were discovered, researchers have successfully performed X-ray spectroscopy to identify the element of a single atom at a time. The achievement takes advantage of improvements to synchrotron X-ray light sources. Until now, the smallest usable sample was at least 10,000 atoms. Now, by combining synchrotron X-rays and quantum tunneling, the researchers detected the element and chemical state of a single atom of iron and terbium.

Researchers studied gene expression in plant/mycorrhizae symbioses by analyzing the roots of a model plant colonized by fungi and using a combination of techniques to measure gene activity in individual cells and visualize gene expression within two-dimensional sections of roots.

When light shines on a semiconductor, it excites the electrons, leaving behind a “hole.” Electrons and these holes attract each other to form excitons, which can interact with other unpaired charges to alter the shape, direction, and/or frequency of a beam of light in the semiconductor. Researchers demonstrated that this response is unprecedently strong in a two-dimensional device made of three atomic layers of the semiconductor tungsten di-selenide.

Leaders from the Department of Energy (DOE) and Lawrence Berkeley National Laboratory celebrated the construction of the foundations for the lab’s newest facility on August 21, 2024. The Seismic Safety and Modernization (SSM) project is replacing the previous cafeteria building, which served the lab for 70 years. (The previous facility could not meet today’s standards for resilience in case of an earthquake, among other issues.) In contrast, the new facility has a 47,000-square-foot state-of-the-art design. It will encompass food service and conference facilities. The building will also be a home for operations services such as security, human resources, and the Health Services Clinic.

A recent study shows that the superconducting edge currents in the topological material molybdenum telluride (MoTe2) can sustain large changes in the “glue” that keeps the superconducting electrons paired. To sustain these changes, the bulk and the edge of MoTe2 must behave differently. This surprise finding will help researchers create and control anyons and aid in the development of future energy-efficient electronics.
