News Release Glenn Roberts Jr. •
A team led by scientists at Berkeley Lab has learned how natural nanoscale defects can enhance the properties of tungsten disulfide, a 2D material.
Topological Matters: Toward a New Kind of Transistor
News Release Glenn Roberts Jr. •
An experiment conducted at Berkeley Lab has demonstrated, for the first time, electronic switching in an exotic, ultrathin material that can carry a charge with nearly zero loss at room temperature. Researchers demonstrated this switching when subjecting the material to a low-current electric field.
Scientists Discover ‘Chiral Phonons’ – Atomic Rotations in a 2-D Semiconductor Crystal
News Release Glenn Roberts Jr. •
A research team has found the first evidence that a shaking motion in the structure of an atomically thin material possesses a naturally occurring circular rotation that could become the building block for a new form of information technology and molecular-scale machines.
New Discovery Could Improve Organic Solar Cell Performance

Scientists who are members of a new energy materials-related science center based at Berkeley Lab have solved a mystery that could lead to gains in efficiency for organic solar cells.
A New Spin on Quantum Computing: Scientists Train Electrons with Microwaves
News Release Glenn Roberts Jr. •
In what may provide a potential path to processing information in a quantum computer, researchers have switched an intrinsic property of electrons from an excited state to a relaxed state on demand using a device that served as a microwave “tuning fork.”
Simplifying Solar Cells with a New Mix of Materials
News Release Glenn Roberts Jr. •
Scientists have simplified the steps to create highly efficient silicon solar cells by applying a new mix of materials to a standard design. The special blend of materials eliminates the need for a process known as doping that steers the device’s properties by introducing foreign atoms. Doping can also degrade performance.
