For the structure under consideration, it is specified in Section 5.3.2. 4 FORMULATIONS OF THE OPTIMIZATION PROBLEM. To obtain a band gap that is as wide as possible at the lowest possible frequency ...

In this brief, we proposed a Ka-band CMOS power amplifier (PA) using stacked structure with cascode-like operation to improve output power. The power stage of the PA consists of one common-source (CS) ...

Understanding the electronic, structural, and dynamical properties of highly oriented pyrolytic graphite (HOPG) and its interface with water is crucial, as its layered structure, vacancy defects, and ...

Topological insulators (TIs) with symmetry-protected surface states offer exciting opportunities for next-generation photonic and optoelectronic device applications. The heterojunctions of TIs and ...

Quantum states that arise and are maintained through the structure of the material used in qubits are called "topological excitations" and are significantly more stable and resilient than others.

Three-dimensional topological insulators (TIs) have become an interesting platform for future high-speed electronics. The massless Dirac fermions in topologically protected surface states (TSSs) ...

A research study led by Oxford University has developed a powerful new technique for finding the next generation of materials needed for large-scale, fault-tolerant quantum computing. This could end a ...
