Issues

Building complex semiconductor structures with features as small as 100 atoms across brings quantum effects to life but challenges fabrication technology.

Ultrafast semiconductor devices form the building blocks of supercomputers. Supercomputers, in turn, are essential for understanding the complex physical phenomena that underlie the devices and for optimizing device performance.

Techniques that use laser pulses as short as three optical cycles are revealing fundamental properties of semiconductors and paving the way for new high‐speed electronic and optical devices.

Understanding nonequilibrium electron transport in III–V compound semiconductors has helped in the development of the fastest bipolar transistors.

When semiconductor devices become small enough, inescapable quantum effects open a whole new range of possibilities for electronic manipulation.
