Double oxide deposition and etching nanolithography for wafer-scale nanopatterning with high-aspect-ratio using photolithography

Jungho Seo, Hanchul Cho, and Ju-kyung Lee et al.

We report a nanolithography technique for the high aspect-ratio nanostructure manufacturing using DODE (double oxide deposition and etching) process. Conventional microfabrication processes are integrated to manufacture nanostructure arrays with sub-100 nm of linewidth. This lithography method is ... [Appl. Phys. Lett. 103, 033105 (2013)] published Tue Jul 16, 2013.

Low-damage high-throughput grazing-angle sputter deposition on graphene

C.-T. Chen, E. A. Casu, and M. Gajek et al.

Despite the prevalence of sputter deposition in the microelectronics industry, it has seen very limited applications for graphene electronics. In this letter, we report systematic investigation of the sputtering induced damages in graphene and identify the energetic sputtering gas neutrals as the ... [Appl. Phys. Lett. 103, 033109 (2013)] published Tue Jul 16, 2013.

Large magnetoresistance in high mobility topological insulator Bi2Se3

Yuan Yan, Li-Xian Wang, and Da-Peng Yu et al.

We report the magnetotransport properties of individual Bi2Se3 nanoplates. The carrier Hall mobility is up to 104 cm2/Vs. A large positive linear magnetoresistance (MR) approaching to 400% without sign of saturation was observed at 14 T. By angular dependence measurements, we demonstrate that the ... [Appl. Phys. Lett. 103, 033106 (2013)] published Tue Jul 16, 2013.

Electron tunneling through graphene-based double barriers driven by a periodic potential

H. P. Ojeda-Collado and C. Rodríguez-Castellanos

Photon-assisted charge transport through a double barrier structure under a time periodic field in graphene is studied. Within the framework of the Floquet formalism and using the transfer matrix method, the transmission probabilities for the central band and sidebands are calculated. A critical p ... [Appl. Phys. Lett. 103, 033110 (2013)] published Tue Jul 16, 2013.

Characterization of local charge distribution of polyethylene terephthalate film and influence as a graphene substrate

Won-Hwa Park, Seok Hwan Noh, and Min Ho Joo et al.

We examine local electrostatic force distribution of polyethylene terephthalate (PET) film surface before and after transferring graphene in order to compare the influence of local electrostatic interaction between graphene and PET film in terms of the sheet resistance value of deposited graphene. ...
