Scientists develop new lithium niobate laser technology

Scientists at EPFL and IBM have developed a new type of laser that could have a significant impact on optical ranging technology. The laser is based on a material called lithium niobate, often used in the field of optical ...

How graphene's electrical properties can be tuned

An accidental discovery in a physicist's laboratory at the University of California, Riverside provides a unique route for tuning the electrical properties of graphene, nature's thinnest elastic material. This route holds ...

New solar cell self-repairs like natural plant systems

(PhysOrg.com) -- Researchers are creating a new type of solar cell designed to self-repair like natural photosynthetic systems in plants by using carbon nanotubes and DNA, an approach aimed at increasing service life and ...

Beyond flash -- memories are made of this

(PhysOrg.com) -- The race is on for a successor to the popular 'flash' memory used in portable devices. European researchers think they have found a candidate in novel materials combined with a simple, easily fabricated 'crossbar' ...

Twisting 2-D materials uncover their superpowers

Two-dimensional (2-D) materials, which consist of a single layer of atoms, have attracted a lot of attention since the isolation of graphene in 2004. They have unique electrical, optical, and mechanical properties, like high ...

With 'ribbons' of graphene, width matters

Using graphene ribbons of unimaginably small widths – just several atoms across – a group of researchers at the University of Wisconsin-Milwaukee (UWM) has found a novel way to "tune" the wonder material, causing the ...
