Time-periodic perturbation can be used to modify the transport properties of the surface states of topological insulators, specifically their chiral tunneling property. Using the scattering matrix method, we study the tunneling transmission of the surface states of a topological insulator under the influence of a time-dependent potential and finite gate bias voltage. It is found that perfect tr...

We report current transmission data through a split-gate constriction fabricated onto a two-dimensional electron system in the integer quantum Hall (QH) regime. Split-gate biasing drives interedge backscattering and is shown to lead to suppressed or enhanced transmission, in marked contrast to the expected linear Fermi-liquid behavior. This evolution is described in terms of particle-hole symme...

We demonstrate active voltage-controlled spectral tuning of mid-infrared plasmonic structures. Extraordinary optical transmission gratings were fabricated on n-doped GaAs epilayers with a HfO2 gate dielectric between the grating and the doped semiconductor. The permittivity of the GaAs was tuned by depleting charge carriers below the top grating gate upon the application of a reverse bias to th...

We study the equilibrium properties of a quantum dot connected to a bulk lead by a single-mode quantum point contact. The ground state energy and other thermodynamic characteristics of the grain show periodic dependence on the gate voltage (Coulomb blockade). We consider the case of almost perfect transmission, and show that the oscillations exist as long as the transmission coefficient of the ...

This paper aims at reducing power and energy dissipation in Transmission Gate Logic (TGL) Multiplexer CMOS circuits comprise of reducing the power supply voltages, power supply current and delay with economical charge recovery logic. This paper designs an 8:1 Multiplexer with CMOS Transmission Gate Logic (TGL) using the Power Gating Technique, which reduces the leakage power and leakage current...

This paper presents the program BOUNCE for animating transients on transmission lines. BOUNCE is used for classroom demonstrations of fundamental concepts such as traveling wave, reflected wave, reflection from an unmatched load, and transmission through junctions and branches. BOUNCE provides a “laboratory” for students to use in verifying homework exercises solved with a lattice diagram. BOUN...

In any digital circuit surface area and power both are very important parameters. In this paper 4bit full adder using transmission gate is designed. To design 4bit full adder two methods are used. First is semi custom design method and second is full custom design method. In first semi custom design method a layout of 4-bit full adder is designed with available width and length of the transisto...

In this survey paper, a literature study on analytical delay models for a CMOS inverter and transmission gate has been done. Inverter followed by Transmission gate structure appears in many CMOS circuit design. Initially, the delay calculation of this entity is done considering them individually, which is not good. In this case, it does not account for the series stack effect that appears while...
