Fabrication of metallic electrodes with nanometer separation by electromigration
A simple yet highly reproducible method to fabricate metallic electrodes with nanometer separation is presented. The fabrication is achieved by passing a large electrical current through a goldExpand
Large scale metal-free synthesis of graphene on sapphire and transfer-free device fabrication.
Metal catalyst-free growth of large scale single layer graphene film on a sapphire substrate by a chemical vapor deposition (CVD) process at 950 °C is demonstrated. A top-gated graphene field effectExpand
Efficient visible light detection using individual germanium nanowire field effect transistors
We report photoconductivity (PC) in individual germanium nanowire field effect transistors (GeFETs). PC measurements with a global illumination reveal that GeFETs can be used as aExpand
A Broadband Circularly Polarized Fabry-Perot Resonant Antenna Using A Single-Layered PRS for 5G MIMO Applications
TLDR
This paper presents the design and the realization of broadband circularly polarized (CP) Fabry–Perot resonant antenna using a single superstrate for the fifth-generation (5G) wireless multiple-input-multiple-output (MIMO) applications. Expand
Graphene nanoribbons formed by a sonochemical graphene unzipping using flavin mononucleotide as a template
Abstract When the width of a graphene nanoribbon (GNR) is only a few nanometers, it possesses semiconducting properties that enable various high-end electronic applications. In this study, we reportExpand
Depolarization effect in optical absorption measurements of one- and two-dimensional nanostructures
We measure absolute optical absorption cross-sections of one- (1D) and two-dimensional (2D) nanostructures using a focused laser beam while varying the numerical aperture (NA) of the focusing lens.Expand
A Rectangular Notch-Band UWB Antenna with Controllable Notched Bandwidth and Centre Frequency
TLDR
This paper presents the design and realization of a compact ultra-wideband (UWB) antenna with a rectangular notch wireless area network (WLAN) band that has controllable notched bandwidth and center frequency. Expand
