Electron-electron interactions in low-dimensional Si:P delta layers

Author(s)
Joseph A. Hagmann, Xiqiao Wang, Ranjit V. Kashid, Pradeep N. Namboodiri, Jonathan E. Wyrick, Scott W. Schmucker, Michael D. Stewart, Richard M. Silver, Curt A. Richter
Key to producing quantum computing devices based on the atomistic placement of dopants in silicon by scanning tunneling microscope (STM) lithography is the

Nonvolatile memory based on redox-active Ruthenium molecular monolayers

Author(s)
Kai Jiang, Sujitra J. Pookpanratana, Tong Ren, Sean Natoli, Brent A. Sperling, Joseph W. Robertson, Curt A. Richter, Sheng Yu, Qiliang Li
A monolayer of diruthenium molecules was self-assembled onto the silicon oxide surface in a semiconductor capacitor structure with a ‘click’ reaction for

QUANTUM-LIMITED 2D SENSORS FOR PH AND BIOSENSING

Author(s)
Arvind K. Balijepalli, Son T. Le, Harish C. Pant, Curt A. Richter
We have developed biosensors based on dual-gated field-effect transistors (FETs) that operate at the quantum capacitance limit. The FETs are fabricated with

Quantum Capacitance-Limited MoS2 Biosensors Enable Remote Label-Free Enzyme Measurements

Author(s)
Son T. Le, Nicholas B. Guros, Robert C. Bruce, Antonio Cardone, Niranjana D. Amin, Siyuan Zhang, Jeffery B. Klauda, Harish C. Pant, Curt A. Richter, Arvind K. Balijepalli
We have demonstrated atomically thin, quantum capacitance-limited, field-effect transistors (FETs) that enable the detection of pH changes with 75-fold higher

Towards superconductivity in p-type delta-doped Si/Al/Si heterostructures

Author(s)
Aruna N. Ramanayaka, Hyun Soo Kim, Joseph A. Hagmann, Roy E. Murray, Ke Tang, Neil M. Zimmerman, Curt A. Richter, Joshua M. Pomeroy, Frederick Meisenkothen, Huairuo Zhang, Albert Davydov, Leonid A. Bendersky
In pursuit of superconductivity in p-type silicon (Si), we are using a single atomic layer of aluminum (Al) sandwiched between a Si substrate and a thin Si epi

Epitaxially-grown self-assembled Bi2Se3/Bi2MnSe4 multilayer heterostructures

Author(s)
Joseph A. Hagmann, Xiang Li, Si-Ning Dong, Sergei Rouvimov, Sujitra J. Pookpanratana, Kin Man Yu, Tatyana Orlova, Curt A. Richter, David G. Seiler, Xinyu Liu, Jacek K. Furdyna, Margaret Dobrowolska
Progress in understanding topologically non-trivial systems offers the promise of predicting novel systems that demonstrate the remarkable properties associated

Interacting nanoscale magnetic cluster arrays in molybdenum oxide bronzes

Author(s)
Joseph A. Hagmann, Son T. Le, Lynn F. Schneemeyer, Joseph A. Stroscio, Tiglet Besara, Theo Siegrist, Curt A. Richter, David G. Seiler
In this study, we examine several reduced ternary molybdates in the family of rare earth molybdenum bronzes produced by electrochemical synthesis with
