Donor-like defects in ZnO substrate materials and ZnO thin films
We have investigated donor-like defects in ZnO substrate material grown by three different methods, and in epitaxial ZnO thin films grown on sapphire by pulsed laser deposition. Temperature dependent Hall...
PublikationenTransport in ZnCoO thin films with stable bound magnetic polarons
Diluted magnetic ZnCoO films with 5 at.% Co have been fabricated by pulsed laser deposition on c-plane sapphire substrates and Schottky and Ohmic contacts have been prepared in top-top configuration. The...
PublikationenPulsed laser deposition of Fe- and Fe, Cu-doped ZnO thin films
Fe- and Fe, Cu-doped ZnO films have been grown on 10×10 mm2 c-plane sapphire by pulsed laser deposition (PLD). The targets were prepared from ZnO, Fe2O3, and/or CuO powder. The structural, electrical...
PublikationenResistive switching in polycrystalline YMnO3 thin films
We report a unipolar, nonvolatile resistive switching in polycrystalline YMnO3 thin films grown by pulsed laser deposition and sandwiched between Au top and Ti/Pt bottom electrodes. The ratio of the resistance...
PublikationenExploiting Memristive BiFeO3 Bilayer Structures for Compact Sequential Logics
Resistive switching devices are considered as one of the most promising candidates for the next generation memories and nonvolatile logic applications. In this paper, BiFeO 3 :Ti/BiFeO 3 (BFTO/BFO) bilayer...
PublikationenAn Energy-Efficient, BiFeO3-Coated Capacitive Switch with Integrated Memory and Demodulation Functions
A capacitive switching behavior is observed in a Si 3 N 4 /p-Si-based metal–insulator–semiconductor (MIS) structure due to the electron tunneling at the Si 3 N 4 /p-Si interface. A BiFeO 3 (BFO) layer...
PublikationenSpin-dependent transport in nanocomposite C:Co films
The magneto-transport properties of nanocomposite C:Co (15 and 40 at.% Co) thin films are investigated. The films were grown by ion beam co-sputtering on thermally oxidized silicon substrates in the temperature...
PublikationenPlasma-Induced Nonvolatile Resistive Switching with Extremely Low SET Voltage in TiOxFy with AgF Nanoparticles
Low power consumption is crucial for the application of resistive random access memory. In this work, we present the bipolar resistive switching in an Ag/TiOxFy/Ti/Pt stack with extremely low switch-on...
PublikationenUnraveling The Origin of Enhanced Field Emission from Irradiated FeCo-SiO2 Nanocomposites: A Combined Experimental and First-Principles Based Study
This work is driven by the vision of engineering planar field emitters with ferromagnetic metal−insulator nanocomposite thin films, using swift heavy ion (SHI) irradiation method. FeCo nanoparticles...
PublikationenForming-Free Resistive Switching in Multiferroic BiFeO3 thin Films with Enhanced Nanoscale Shunts
A controlled shunting of polycrystalline oxide thin films on the nanometer length scale opens the door to significantly modify their transport properties. In this paper, the low energy Ar+ irradiation...
