Journal ArticleDOI
Manipulating thermal conductance at metal-graphene contacts via chemical functionalization.
Patrick E. Hopkins,M. Baraket,Edward V. Barnat,Thomas E. Beechem,Sean P. Kearney,John C. Duda,John C. Duda,Jeremy T. Robinson,Scott G. Walton +8 more
TL;DR: Results demonstrate plasma-based functionalization of graphene surfaces is a viable approach to manipulate the thermal boundary conductance.
Journal ArticleDOI
Electrical, Thermal, and Mechanical Characterization of Silicon Microcantilever Heaters
Jungchul Lee,Thomas E. Beechem,Tanya L. Wright,Brent A. Nelson,Samuel Graham,William P. King +5 more
TL;DR: In this paper, the authors describe detailed mechanical, electrical, and thermal characterization and calibration of AFM cantilevers having integrated solid-state heaters, which have been applied to metrology, thermophysical property measurements, and nanoscale manufacturing.
Journal ArticleDOI
Effects of surface roughness and oxide layer on the thermal boundary conductance at aluminum/silicon interfaces
TL;DR: In this article, the authors measured the room-temperature thermal boundary conductance of aluminum films grown on silicon substrates subjected to various pre-Al-deposition surface treatments with a pump-probe thermoreflectance technique.
Journal ArticleDOI
Evidence for Interlayer Coupling and Moire Periodic Potentials in Twisted Bilayer Graphene
Taisuke Ohta,Jeremy T. Robinson,Peter J. Feibelman,Aaron Bostwick,Eli Rotenberg,Thomas E. Beechem +5 more
TL;DR: A study of the valence band dispersion of twisted bilayer graphene using angle-resolved photoemission spectroscopy and ab initio calculations finds minigaps appeared at the Brillouin zone boundaries of the moiré superlattice formed by the misorientation of the two graphene layers.
Journal ArticleDOI
Lithographically Defined Three-Dimensional Graphene Structures
Xiaoyin Xiao,Thomas E. Beechem,Michael T. Brumbach,Timothy N. Lambert,Danae J. Davis,J. R. Michael,Cody M. Washburn,Joseph Wang,Susan M. Brozik,David R. Wheeler,D. Bruce Burckel,Ronen Polsky +11 more
TL;DR: It is demonstrated how prestructured PPF can be chemically converted into hollow, interconnected 3D multilayered graphene structures having pore sizes around 500 nm, which makes this material a promising candidate for microbattery and sensing applications.
