Journal ArticleDOI
Emerging memories: resistive switching mechanisms and current status.
Doo Seok Jeong,Reji Thomas,Ram S. Katiyar,James F. Scott,Hermann Kohlstedt,A. Petraru,Cheol Seong Hwang +6 more
TL;DR: The review ends with the current status of RRAMs in terms of stability, scalability and switching speed, which are three important aspects of integration onto semiconductors.
Journal ArticleDOI
Temperature-Dependent Raman Studies and Thermal Conductivity of Few-Layer MoS2
TL;DR: In this paper, the temperature dependence of in-plane E2g and out-of-plane A1g Raman modes in high-quality few-layer MoS2 (FLMS) prepared using a high-temperature vapor phase method was investigated using transmission electron microscopy.
Journal ArticleDOI
β phase and γ-β metal-insulator transition in multiferroic BiFeO3
Ratnakar Palai,Ram S. Katiyar,Hans Schmid,Paul Tissot,Stewart J. Clark,John Robertson,Simon A. T. Redfern,Gustau Catalan,James F. Scott +8 more
TL;DR: In this paper, the authors report on extensive experimental studies on thin film, single crystal, and ceramics of multiferroic bismuth ferrite BiFeO3 using differential thermal analysis, high-temperature polarized light microscopy, hightemperature x-ray diffraction, dc conductivity, optical absorption and reflectivity, and domain imaging.
