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.”
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.
Berkeley Lab researchers have discovered a new mechanism for assembling two-dimensional molecular “islands” that could be used to modify graphene at the nanometer scale for use in electronic devices.
An important step towards next-generation ultra-compact photonic and optoelectronic devices has been taken with the realization of a two-dimensional excitonic laser. Berkeley Lab researchers have embedded a monolayer of tungsten disulfide into a microdisk resonator to achieve bright excitonic lasing at visible light wavelengths.
Berkeley Lab researchers have confirmed that single-crystal black phosphorous nanoribbons display a strong in-plane anisotropy in thermal conductivity, an experimental revelation that should facilitate the future application of this highly promising material to electronic, optoelectronic and thermoelectric devices.
Berkeley Lab researchers have produced the first atomically thin 2D sheets of organic-inorganic hybrid perovskites. These ionic materials exhibit optical properties not found in 2D covalent semiconductors such as graphene, making them promising alternatives to silicon for future electronic devices.
Working at the Molecular Foundry, Berkeley Lab researchers used their “Campanile” nano-optical probe to make some surprising discoveries about molybdenum disulfide, a member of the “transition metal dichalcogenides (TMDCs) semiconductor family whose optoelectronic properties hold great promise for future nanoelectronic and photonic devices.
Researchers from Columbia University and Berkeley Lab have created the world’s highest-performance single-molecule diode. Development of a functional single-molecule diode is a major pursuit of the electronics industry.
Working at the Advanced Light Source, Berkeley Lab researchers have observed “Luttinger-liquid” plasmons in metallic single-walled nanotubes. This holds great promise for novel plasmonic and nanophotonic devices over a broad frequency range, including telecom wavelengths.
Berkeley Lab researchers have developed a bright, high-repetition-rate laser source that can generate XUV light for ultrafast materials dynamics and electronic structure studies.
