Electrons caught in the act

Scientists combine scanning tunneling microscopy with ultrafast spectroscopy to image the motion of electrons with unprecedented resolution, which may lead to advances in semiconductors and optoelectronics.

Ultrawide bandgap gives material high-power potential

Researchers have found a way to grow a single crystalline layer of alpha-aluminum gallium oxide that has the widest energy bandgap to date - a discovery that clears the way for new semiconductors that will handle higher voltages, higher power densities and higher frequencies than previously seen.

Researchers develop hydrogen-bonded organic frameworks based electrochromic film

Researchers have developed an electrochromic hydrogen-bonded organic frameworks film with long cycle life, facile modification, easy recycling and regeneration prepared via electrophoretic deposition rapidly and facile.

A sharp new eye to view atoms and molecules

A new X-ray laser oscillator generates types of pulses that were never before possible. The pulses are stable, intense, and of ultrashort duration and have a well-defined wavelength. This ability opens new possibilities in experiments and research.

New metamaterial offers reprogrammable properties

Scientists have developed a metamaterial whose mechanical properties can be reprogrammed on demand and whose internal structure can be modified by applying a magnetic field.
