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
Crossing an Interface: Ferroelectric Control of Tunnel Currents in Magnetic Complex Oxide Heterostructures
TL;DR: In this article, experiments indicate that ionic displacements associated with the polarization reversal in the ferroelectric barrier affect the complex band structure at ferromagnetic-ferroelectric interfaces.
Journal ArticleDOI
Giant electrode effect on tunnelling electroresistance in ferroelectric tunnel junctions
R. Soni,A. Petraru,Paul Meuffels,O. Vavra,Martin Ziegler,Seong Keun Kim,Doo Seok Jeong,N. A. Pertsev,Hermann Kohlstedt +8 more
TL;DR: A giant electrode effect on the TER of these asymmetric FTJs is demonstrated, attributed to the microscopic interfacial effect of ferroelectric origin, supported by the observation of redox-based resistance switching at much higher voltages.
Journal ArticleDOI
Probing Cu doped Ge0.3Se0.7 based resistance switching memory devices with random telegraph noise
R. Soni,Paul Meuffels,A. Petraru,Martin Weides,Carsten Kügeler,Rainer Waser,Hermann Kohlstedt +6 more
TL;DR: In this article, the influence of temperature and electric field on the random telegraph noise (RTN) resistance fluctuations in Cu doped Ge0.3Se0.7 based RRAM cells is studied.
Journal ArticleDOI
Method to distinguish ferroelectric from nonferroelectric origin in case of resistive switching in ferroelectric capacitors
Hermann Kohlstedt,A. Petraru,K. Szot,A. Rüdiger,Paul Meuffels,H. Haselier,Rainer Waser,Valanoor Nagarajan +7 more
TL;DR: In this article, the resistive switching effect in SrRuO3∕PbZr0.2Ti0.8O3 ∕Pt ferroelectric capacitors was investigated using a conductive atomic force microscope.
