Some of us are anxiously awaiting the photonics revolution, where photons will band together to overthrow the tyranny of electrons. One of the perpetual problems that's slowing up the revolution is ...

A major challenge in modern surface science is to create ordered arrays of covalently linked organic nanostructures. By doping molecular electronic bands into highly conductive states, these ...

Semiconductor materials play an important part in developing nanophotonic technologies. Semiconductors are used for generating controllable photons as well as for confining and exploiting them for ...

In 2008, Michael Ruck was frustrated. The inorganic chemist at Technical University Dresden was trying to figure out a way to build even smaller transistors than already existed, making nanowires of ...

Researchers at Lund University, Sweden, have grown single continuous GaAs nanowires consisting of segments of pure wurtzite and zincblende phases. Using photoluminescence spectroscopy, they found that ...

Bandgap refers to a region of an element’s crystal’s electronic band structure through which electrons can’t pass. Also referred to as an energy gap, bandgap is a concept in solid-state physics and ...

Many modern electronic devices we use daily owe their existence to the process of semiconductor doping. Doped semiconductors are the result of careful modifications ...

A transistor is an element that amplifies electrical signals and controls the on/off of currents by electrical signals. Transistors are necessary parts for assembling logic circuits, and it is no ...
