Journal ArticleDOI
Elastomeric Transistor Stamps: Reversible Probing of Charge Transport in Organic Crystals
Vikram C. Sundar,Jana Zaumseil,Vitaly Podzorov,Etienne Menard,R. L. Willett,Takao Someya,Michael Gershenson,John A. Rogers +7 more
TL;DR: This method, which eliminates exposure of the fragile organic surface to the hazards of conventional processing, enables fabrication of rubrene transistors with charge carrier mobilities as high as ∼15 cm2/V·s and subthreshold slopes as low as 2nF·V/decade·cm2.
Journal ArticleDOI
Additive, nanoscale patterning of metal films with a stamp and a surface chemistry mediated transfer process: Applications in plastic electronics
TL;DR: In this paper, the authors describe a method for contact printing metal patterns with nanometer features over large areas, which relies on tailored surface chemistries to transfer metal films from the raised regions of a stamp to a substrate when these two elements are brought into intimate physical contact.
Journal ArticleDOI
Interfacial Chemistries for Nanoscale Transfer Printing
TL;DR: A patterning technique that uses self-assembled monolayers and other surface chemistries for guiding the transfer of material from relief features on a stamp to a substrate capable of nanometer resolution is described.
Journal ArticleDOI
Scanning Single-Electron Transistor Microscopy: Imaging Individual Charges
M. J. Yoo,T.A Fulton,H. F. Hess,R. L. Willett,L. N. Dunkleberger,R. J. Chichester,Loren Pfeiffer,K. W. West +7 more
TL;DR: The SETSE has been used to image and measure depleted regions, local capacitance, band bending, and contact potentials at submicrometer length scales on the surface of this semiconductor sample.
Journal ArticleDOI
Experimental demonstration of a Fermi surface at one-half filling of the lowest Landau level.
TL;DR: The first direct observation of the cyclotron motion of new quasiparticles in a 2D electron system near 1/2 filling factor is reported, and resonance of a surface sound wave with cyclotrons orbits of charge carriers is observed.
