Heterostructures fabricated by the direct bonding of SiC polytype and Si may have interesting physical and electrical attributes. Silicon (Si) also has been accepted as a promising material for wide range of electronic, optical and optoelectronic applications. The most prominent polytypes (among 200 types) of SiC like 3C-SiC, 4H-SiC and 6H-SiC, have distinctive electrical and physical attributes that make them promising candidates for high performance optoelectronic applications. These properties make SiC highly suitable for high temperature, high frequency, and high power electronics applications. Keywords: Heterojunction, InGaAs/InP, TCAD, Analog parameters.Ībstract: In the last decades, silicon carbide (SiC) based heterostructures have gained a remarkable place in research field due to their exceptional properties. The impact of InGaAs/InP hetero structure and barrier thickness variation claims GAA MOSFET as a promising candidate for VLSI applications. It has been seen from the presented results that the influence of barrier thickness variation gives the notable improvement in drain current. Based on the simulation results it is investigated that the effect of the all electrical parameters in the nanoscale devices. The electrical parameters such as surface potential, electric field, transfer characteristics, output characteristics, transconductance and output conductance is carried out and analyzed by varying the barrier thickness from 1 nm to 4 nm. A detailed study on the impact of Barrier thickness on different analog and digital performance for an InGaAs/InP hetero structure GAA MOSFET is carried out by using TCAD device simulation. These achievements highlight the applications of graphene in quantum technology, a technology sector that demands new materials to address key issues as it matures towards commercial scale.Abstract: In this work, we have analyzed the digital and analog performance for InGaAs/InP heterojunction Gate all around MOS structure. The device is made of graphene integrated in a superconducting Josephson junction and is 100,000 times faster than microwave bolometers made of other materials. In follow-up research, Efetov and his colleagues constructed a graphene-based bolometer that has the highest sensitivity allowed by thermodynamics. Room-temperature operation meant that the device could be used to monitor heat escape from buildings, or to bridge the terahertz gap in astronomy. To achieve high sensitivity, the team used a different approach, coupling the graphene to a photonic nanocavity. Previously, a different team led by Dmitri Efetov made highly-sensitive graphene bolometers that ran at room temperatures. Illustration: Graphene quantum bolometer (Courtesy: Heikka Valja). With time constants of less than half a microsecond, these graphene bolometers match the timescales required for superconducting qubit detection. Using graphene also increased the detector speed by 100 times compared to previously used bolometers that the team built from a gold-palladium alloy. The graphene device, reported by a team from Finland in the journal Nature, makes use of the small heat capacity of graphene which makes the material heat up much for each photon absorbed. However, overcoming the challenges of low energies of microwave photons and high speed required for qubit detection has been elusive. Bolometers capable of detecting single microwave photons would be very useful in creating quantum computers and other technologies that use quantum bits (qubits). A measure of device temperature yields the intensity of the radiation. The device, made of a single sheet of graphene, could find a range of applications in quantum technologies, radio astronomy and even in search for dark matter.Ī bolometer is a device that detects incoming radiation by absorbing photons and converting them to heat. Researchers have created a bolometer, a heat detecting device, that can detect single microwave photons and is compatible with quantum computing.
