Berkeley Lab Researchers Observe Shortest Wavelength Plasmons Ever in Single Walled Nanotubes

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.

A Bright Light for Ultrafast Snapshots of Materials

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.

Defects Can “Hulk-Up” Materials

A Berkeley Lab study has shown that just as exposure to gamma radiation transforms Bruce Banner into fictional superhero the Hulk, exposure to alpha-particle radiation can transform thermoelectric materials into far more powerful versions of themselves.

Channeling Valleytronics in Graphene

Berkeley Lab researchers, working at the Advanced Light Source, have discovered topologically protected 1D electron conducting channels at the domain walls of bilayer graphene that should prove useful for valleytronics.

On the Road to Spin-orbitronics

Berkeley Lab researchers have discovered a new way of manipulating the magnetic domain walls in ultrathin magnets that could one day revolutionize the electronics industry through a technology called “spin-orbitronics.”

New Pathway to Valleytronics

Berkeley Lab researchers have uncovered a promising new pathway to valleytronics, a potential quantum computing technology in which information is coded based on the wavelike motion of electrons moving through certain 2D semiconductors.

Solving an Organic Semiconductor Mystery

Organic semiconductors are prized for light emitting diodes (LEDs), field effect transistors (FETs) and photovoltaic cells. As they can be printed from solution, they provide a highly scalable, cost-effective alternative to silicon-based devices. Uneven performances, however, have been a persistent problem. That’s now changed.

From the Bottom Up: Manipulating Nanoribbons at the Molecular Level

Researchers at Lawrence Berkeley National Laboratory and the University of California, Berkeley, have developed a new precision approach for synthesizing graphene nanoribbons from pre-designed molecular building blocks. Using this process the researchers have built nanoribbons that have enhanced properties—such as position-dependent, tunable bandgaps—that are potentially very useful for next-generation electronic circuitry.

Piezoelectricity in a 2D Semiconductor

Berkeley Lab researchers have opened the door to low-power off/on switches in micro-electro-mechanical systems (MEMS) and nanoelectronic devices, as well as ultrasensitive bio-sensors, with the first observation of piezoelectricity in a free standing two-dimensional semiconductor.

Switching to Spintronics

Berkeley Lab researchers used an electric field to reverse the magnetization direction in a multiferroic spintronic device at room temperature, a demonstration that points a new way towards spintronics and smaller, faster and cheaper ways of storing and processing data.
