M. Mumtaz Qazilbash,M. Brehm,Byung-Gyu Chae,Pei-Chun Ho,Gregory O. Andreev,Bong-Jun Kim,Sun Jin Yun,Alexander V. Balatsky,M. B. Maple,Fritz Keilmann,Hyun-Tak Kim,Dimitri Basov +11 more
TL;DR: The electronic properties of a prototypical correlated insulator vanadium dioxide in which the metallic state can be induced by increasing temperature is reported, setting the stage for investigations of charge dynamics on the nanoscale in other inhomogeneous correlated electron systems.
Journal ArticleDOI

Hyun-Tak Kim,Yong Wook Lee,Bong-Jun Kim,Byung-Gyu Chae,Sun Jin Yun,Kwang-Yong Kang,Kang-Jeon Han,Ki-Ju Yee,Yong-Sik Lim +8 more
TL;DR: In femtosecond pump-probe measurements, the appearance of coherent phonon oscillations indicating the rutile metal phase of VO2 does not occur simultaneously with the first-order metal-insulator transition (MIT) near 68 degrees C is indicated.

Method of forming a thin film in a semiconductor device
TL;DR: In this paper, a thin film is formed by alternately repeating an atomic layer deposition (ALD) method and a plasma enhanced ALD method and further by adjusting the ratio of repetition times of the methods, so that it is possible to adjust and estimate the growth rate, density, and material properties such as refraction index, dielectric constant, electric resistance, etc.
Journal ArticleDOI
Temperature dependence of the first-order metal-insulator transition in VO2 and programmable critical temperature sensor
Bong-Jun Kim,Yong Wook Lee,Byung-Gyu Chae,Sun Jin Yun,Soo-Young Oh,Hyun-Tak Kim,Yong-Sik Lim +6 more
TL;DR: In this paper, the first-order metal-insulator transition (MIT, jump) is controlled by an applied voltage and temperature, and an intermediate monoclinic metal phase between the MIT and the structural phase transition (SPT) is observed.
