Multi-scale alignment to buried atom-scale devices using Kelvin probe force microscopy

February 24, 2024
Author(s)
Pradeep Namboodiri, Jonathan Wyrick, Gheorghe Stan, Xiqiao Wang, Fan Fei, Ranjit Kashid, Scott Schmucker, Richard Kasica, Bryan Barnes, Michael Stewart, Richard M. Silver
Fabrication of quantum devices by atomic scale patterning with a Scanning Tunneling Microscope (STM) has led to the development of single/few atom transistors, few-donor/quantum dot devices for spin manipulation and arrayed few-donor devices for analog

Atomic force microscopy for nanoscale mechanical property characterization

November 10, 2020
Author(s)
Gheorghe Stan, Sean King
Over the past several decades, atomic force microscopy (AFM) has advanced from a technique used primarily for surface topography imaging to one capable of characterizing a range of chemical, mechanical, electrical, and magnetic material properties with sub

Doping of MoTe2 via surface charge-transfer in ambient air

March 19, 2020
Author(s)
Gheorghe Stan, Cristian Ciobanu, Sri Ranga Jai Likith, Asha Rani, Sergiy Krylyuk, Albert Davydov
Doping is a key process that facilitates the use of semiconductors for electronic and optoelectronic devices, by which the concentration and type of majority carriers (electrons or holes) can be modified controllably to achieve desired conduction

Thermal conductivity of entropy stabilized oxides: approaching the minimum limit in single crystal solid solutions through charge induced atomic-scale disorder

September 17, 2018
Author(s)
Gheorghe Stan, Jeffrey Braun, Christina Rost, Mina Lim, Ashutosh Giri, David Olson, George Kotsonis, Donald Brenner, Jon-Paul Maria, Patrick Hopkins
Manipulating a crystalline material’s configurational entropy though the introduction of unique atomic species can produce novel materials with desirable mechanical and electrical properties. From a thermal transport perspective, large differences between

PEGylation of zinc nanoparticles amplifies their ability to enhance olfactory responses to odorant

December 20, 2017
Author(s)
Melissa Singletary, Samantha Hagerty, Shinichiro Muramoto, Yasmine Daniels, William A. MacCrehan, Gheorghe Stan, June W. Lau, Oleg Pustovyy, Ludmila Globa, Edward E. Morrison, Iryna Sorokulova, Vitaly Vodyanoy
Responses of olfactory sensory neurons to odorants are intensely enhanced with the addition of small endogenous and engineered zinc nanoparticles, as shown by physiological experiments. The highest enhancement was recorded with 1.2 nm non-oxidized zinc

Nanoscale Structure-Property Characterization of a Nanopatterned Hybrid Organic-Inorganic Nanoporous Material

April 13, 2017
Author(s)
Gheorghe Stan, Richard S. Gates, Qichi Hu, Kevin Kjoller, Craig Prater, Alan Myers, Kanwal Singh, Ebony Mays, Sean W. King
The continued advancement of nanostructured materials and exploitation of nanoscale size effects will ultimately require understanding material structure-property relationships at the nanoscale. Despite a plethora of metrologies capable of characterizing
