Variable Electrical Responses in Epitaxial Graphene Nanoribbons
C. -C. Yeh, S. M. Mhatre, N. T. M. Tran +7
We have demonstrated the fabrication of both armchair and zigzag epitaxial graphene nanoribbon (GNR) devices on 4H-SiC using a polymer-assisted sublimation growth method. The pheno…
Star-Mesh Quantized Hall Array Resistance Devices
Dean G. Jarrett, Ching-Chen Yeh, Shamith U. Payagala +10
Advances in the development of graphene-based technology have enabled improvements in DC resistance metrology. Devices made from epitaxially grown graphene have replaced the GaAs-b…
Quantum Entropic Effects in the Liquid Viscosities of Hydrogen, Deuterium, and Neon
Ian Bell, Jacob W. Leachman, Albert F. Rigosi +1
The extremely low temperatures have limited the availability and accuracy of experimental thermophysical property measurements for cryogens, particularly transport properties. Trad…
Optical Signatures of Strain Differences in Epitaxial Graphene Nanoribbons
Heather M. Hill, Ching-Chen Yeh, Swapnil M. Mhatre +6
We demonstrate the preparation of both armchair and zigzag epitaxial graphene nanoribbons (GNRs) on 4H-SiC using a polymer-assisted, sublimation growth method. Historically, the pr…
