Ultrasmall α-Fe2O3 Superparamagnetic Nanoparticles with High Magnetization Prepared by Template-Assisted Combustion Process
Khachatur V. Manukyan,Yong-Siou Chen,Sergei Rouvimov,Peng Li,Xiang Li,Sining Dong,Xinyu Liu,Jacek K. Furdyna,Alexei O. Orlov,Gary H. Bernstein,Wolfgang Porod,Sergey Roslyakov,Alexander S. Mukasyan +12 more
TL;DR: In this paper, a template-assisted combustion-based method was developed to synthesize the ultrasmall (below 5 nm) α-Fe2O3 nanoparticles, where iron and ammonium nitrate were used as oxidizers, glycine as a "fuel" and mesoporous silica (SBA-15) as a template.
Journal ArticleDOI
Quantum-Dot Cellular Automata:Line and Majority Logic Gate
Gregory L. Snider,Alexei O. Orlov,Islamshah Amlani,Gary H. Bernstein,Craig S. Lent,James L. Merz,Wolfgang Porod +6 more
TL;DR: An introduction to the operation of quantum-dot cellular automata is presented, along with recent experimental results, and the basic building blocks of the QCA architecture, such as AND, OR, and NOT are presented.
Journal ArticleDOI
Power gain in a quantum-dot cellular automata latch
Ravi K. Kummamuru,John Timler,Géza Tóth,Craig S. Lent,Rajagopal Ramasubramaniam,Alexei O. Orlov,Gary H. Bernstein,Gregory L. Snider +7 more
TL;DR: An experimental demonstration of power gain in quantum-dot cellular automata (QCA) devices, where charge configurations in quantum dots are used to encode and process binary information.
Journal ArticleDOI
Shape Engineering for Controlled Switching With Nanomagnet Logic
Michael Niemier,Edit Varga,Gary H. Bernstein,Wolfgang Porod,M.T. Alam,Aaron Dingler,Alexei O. Orlov,Xiaobo Sharon Hu +7 more
TL;DR: In this paper, the authors demonstrate that in circuits and systems that comprised of nanoscale magnets, magnet-shape-dependent switching properties can be used to perform Boolean logic and demonstrate that magnet shape can facilitate nonmajority-gate-based, reduced footprint logic.
Journal ArticleDOI
Clocked quantum-dot cellular automata shift register
Alexei O. Orlov,Ravi K. Kummamuru,Rajagopal Ramasubramaniam,Craig S. Lent,Gary H. Bernstein,Gregory L. Snider +5 more
TL;DR: In this paper, the authors present an experimental demonstration of a two-stage shift register (SR) and use it to mimic the operation of a multi-stage SR. Error-bit rates for binary switching operations in a metal tunnel junction device are experimentally investigated, and discussed for future molecular QCAs.
