Imaging 'Invisible' Dopant Atoms in Semiconductor Nanocrystals

In semiconductor nanocrystals, the physical effects of deliberately included impurities, called dopants, may depend on the dopant position with the crystal. 

Why Most Plastics Can't be Metals

Conductive polymers, i.e. plastics, that conduct electricity, are important in science and technology as they offer the potential for cheap, flexible electronic devices.

High Efficiency Silicon Nanocrystal Light Emitting Devices

Hybrid light-emitting devices based on organic semiconductors and inorganic semiconductor nanocrystals are of great interest for applications in optical displays and solid-state light sources.

Patterned Graphene "Scrap" Grows into Continuous "Patchwork Quilt"


New technique produces heterojunctions in single-atom-thick graphene

Stressing the Most Important (Dirac) Points

Recent physics research shows how spin-orbit coupling can rearrange electronic bands in a solid to make a "topological insulator" a new quantum phase of matter that is guaranteed to have conductive surfaces even though its bulk is insulating. What happens if you take a topological insulator and compress or expand it?
