Video: Creating ultrasharp STM, AFM probes for superior resolution and durability

By / July 10, 2012

Researchers at the University of Illinois have literally made a pointed improvement in microscopic probe tips. Led by Joe Lyding, a professor of electrical and computer engineering, the investigators developed a new microscope probe-sharpening technique that can improve and retain the resolution of  scanning tunneling atomic force microscopy and improve the workflow by cutting tip replacement downtime. According…

Pump-and-probe laser method shines new light on rapid phase transitions

By / March 16, 2012

Lost vibrations: In the insulating state, the VO2 crystal structure vibrates at four well-defined frequencies when hit by a low power laser pulse. These vibrations modulate the reflectivity over time as shown in the left image. In the right image, the power of the laser has been turned up and the VO2 has stopped vibrating,…
