Using a specially developed etching apparatus, a team at HZB has now produced mesoporous silicon layers with countless tiny pores and investigated their electrical and thermal conductivity.

In fact, conductivity at the nanoscale is completely independent of the added impurities, or dopants, that usually control silicon's electrical properties, the team reports.

While studying different cross-linking structures in silicone, the research team stumbled upon the potential for electrical conductivity in a copolymer, which is a polymer chain containing two ...

Gallium nitride, a semiconductor renowned for its efficiency and high-speed capabilities, has long been recognized as a ...

Once considered merely insulating, a change in the angle between silicon and oxygen atoms opens a pathway for electrical charge to flow. A breakthrough discovery from the University of Michigan has ...

Silicon anodes are generally viewed as the next development in lithium-ion battery technology. Silicon’s ability to absorb more charge translates to longer battery life and smaller batteries, if ...

Carbon also improves electrical conductivity, ensuring better lithium-ion flow for improved efficiency. The trade-off is that Si/C anodes don’t achieve pure silicon’s full 10x capacity boost.

When graduate student Pengpeng Zhang successfully imaged a piece of silicon just 10 nanometers-or a millionth of a centimeter-in thickness, she and her University of Wisconsin-Madison co ...
