The Editor's Choice article by Min Soo Youm et al. (pp. 2657–2661) investigates the physical properties of phase-change random access memory (PRAM) devices made of Ge2Sb2Te5 (GST) sputtered thin films. To observe changes in the atomic structure the authors prepared specimens for transmission electron microscopy (TEM) and measured the threshold voltage as well as initial resistance variation of phase-change devices.

Corresponding author Dr. Yong Tae Kim is a principal scientist in the Semiconductor Materials and Devices Laboratory of the Korea Institute of Science and Technology. His research activities are divided into three main areas: materials and devices related to non-volatile memory applications (FeRAM, PRAM, ReRAM), second, bio-sensors and bio-materials, and, third, nano-materials and devices.
