Journal ArticleDOI
Memristive switching mechanism for metal/oxide/metal nanodevices.
Jianhua Yang,Matthew D. Pickett,Xuema Li,Douglas A. A. Ohlberg,Duncan Stewart,R. Stanley Williams +5 more
TL;DR: Experimental evidence is provided to support this general model of memristive electrical switching in oxide systems, and micro- and nanoscale TiO2 junction devices with platinum electrodes that exhibit fast bipolar nonvolatile switching are built.
Journal ArticleDOI
Sequence-Specific Label-Free DNA Sensors Based on Silicon Nanowires
TL;DR: Highly sensitive and sequence-specific DNA sensors were fabricated based on silicon nanowires with single stranded probe DNA molecules covalently immobilized on the nanowire surfaces, recognizing label-free complementary ss-DNA in sample solutions when the target DNA was hybridized with the probe DNA attached on the SiNW surfaces.
Journal ArticleDOI
Nanoscale molecular-switch crossbar circuits
Yong Chen,Gun Young Jung,Douglas A. A. Ohlberg,Xuema Li,Duncan Stewart,Jan O. Jeppesen,Kent A. Nielsen,J. Fraser Stoddart,R. Stanley Williams +8 more
TL;DR: In this paper, the authors describe the fabrication and testing of nanoscale molecular-electronic circuits that comprise a molecular monolayer of [2] rotaxanes sandwiched between metal nanowires to form an 8 × 8 crossbar within a 1 µm 2 area.
Journal ArticleDOI
Memristor―CMOS Hybrid Integrated Circuits for Reconfigurable Logic
Qiangfei Xia,Warren Robinett,Cumbie Michael W,Neel Banerjee,Thomas J. Cardinali,Jianhua Yang,Wei Wu,Xuema Li,William M. Tong,Dmitri B. Strukov,Gregory S. Snider,Gilberto Medeiros-Ribeiro,R. Stanley Williams +12 more
TL;DR: Hybrid reconfigurable logic circuits were fabricated by integrating memristor-based crossbars onto a foundry-built CMOS (complementary metal-oxide-semiconductor) platform using nanoimprint lithography, as well as materials and processes that were compatible with the CMOS.
Journal ArticleDOI
Nanoscale molecular-switch devices fabricated by imprint lithography
Yong Chen,Douglas A. A. Ohlberg,Xuema Li,Duncan Stewart,R. Stanley Williams,Jan O. Jeppesen,Jan O. Jeppesen,Kent A. Nielsen,Kent A. Nielsen,J. Fraser Stoddart,Deirdre L. Olynick,Erik H. Anderson +11 more
TL;DR: In this article, a single molecular monolayer of bistable rotaxanes sandwiched between two 40-nm metal electrodes was fabricated using imprint lithography, and it was observed that it has high on-off ratios and reversible switching properties.
