We report on the nanosheet-thickness effects on the performance of top-gate MoS(2) field-effect transistors (FETs), which is directly related to the MoS(2) dielectric constant. Our top-gate nanosheet FETs with 40 nm thin Al(2)O(3) displayed at least an order of magnitude higher mobility than those of bottom-gate nanosheet FETs with 285 nm thick SiO(2), benefiting from the dielectric screening b...

The millimeter Wave transmission provides large bandwidth for data transfer which can satisfy the 5th generation mobile network architecture three main features: High rate, Low latency, Mass Connectivity. Due to high propagation attenuation characteristic of Wave, Directivity Antenna Array greatly increase transmitting distance. antenna dimensions are designed relative wave length better radiat...

BACKGROUND Tissue dielectric properties are specific to physiological changes and consequently have been pursued as imaging biomarkers of cancer and other pathological disorders. However, a recent study (Phys Med Biol 52:2637-2656, 2007; Phys Med Biol 52:6093-6115, 2007), which utilized open-ended dielectric probing techniques and a previously established sensing volume, reported that the diele...

The demand for improved food quality has been accompanied by a technological boost. This fact enhances the possibility of improving the quality of horticultural products, leading towards healthier consumption of fruits and vegetables. A better electrical characterization of the dielectric properties of fruits and vegetables is required for this purpose. Moreover, a focused study of dielectric s...

We report the fabrication of and investigations into the dielectric and thermal properties of epoxy/boron nitride nanotube (BNNT) composites. It was found that BNNT fillers can effectively adjust the dielectric constant of epoxy. Moreover, the thermal conductivity of epoxy was improved by up to 69 % with 5 wt % BNNTs. Our studies indicate that BNNTs are promising nanofillers for polymers, to ob...

Studies of Metal–insulator–metal (MIM) capacitors having high-κ La2O3\HfO2 dielectric stacks are fabricated using Pulse Laser Deposition (PLD) is carried out. Nano-sized La2O3\HfO2 dielectric stacks are deposited using PLD system under optimized pressure, substrate temperature and numbers of shots inside argon ambient chamber. The morphology of dielectric stacks is examined using AFM and the th...

We have investigated the focusing properties of surface plasmon polariton floating dielectric lenses. An analysis of the scattering characteristics of surface plasmon polaritons using a floating dielectric block shows that the air-gap thickness between a floating dielectric block and a metal substrate can be an effective dynamic variable for modulating the amplitude and phase of the transmissio...

The dielectric properties of reactive mesogens before and after photopolymerization were investigated. Commercially available nematic reactive mesogens (RMS03-013C, Merck) were measured and found to be dual-frequency liquid crystals. The property arose from the δ-relaxation process that was caused by rotational fluctuations parallel to the molecule's long axis. After polymerization, the polymer...

Semiconductors with a moderate bandgap have enabled modern electronic device technology, and the current scaling trends down to nanometer scale have introduced two-dimensional (2D) semiconductors. The bandgap of a semiconductor has been an intrinsic property independent of the environments and determined fundamental semiconductor device characteristics. In contrast to bulk semiconductors, we de...
