Monolayer MoS2 Bandgap Modulation by Dielectric Environments and Tunable Bandgap Transistors [PDF]
Scientific Reports, 2016 AbstractSemiconductors 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 ...

1999 IEEE LEOS Annual Meeting Conference Proceedings. LEOS'99. 12th Annual Meeting. IEEE Lasers and Electro-Optics Society 1999 Annual Meeting (Cat. No.99CH37009), 2003 Photonic bandgap fibers are described using a new Kagome cladding structure. These fibers may potentially guide light in low-index regions. Such fibers offer new dispersion properties, and large design flexibility.

Plasma etching of wide bandgap and ultrawide bandgap semiconductors [PDF]
Journal of Vacuum Science & Technology A, 2020 The precise patterning of front-side mesas, backside vias, and selective removal of ternary alloys are all needed for power device fabrication in the various wide bandgap (AlGaN/GaN, SiC) and ultrawide bandgap (high Al-content alloys, boron nitride, Ga2O3, diamond) semiconductor technologies.

Above‐Bandgap Photovoltages in Antiferroelectrics [PDF]
Advanced Materials, 2016 The first antiferroelectric solar cell is presented. This study shows that antiferroelectric thin-film photovoltaic current can be switched on when biased into the polar phase to generate abovebandgap photovoltages in excess of 100 V and photovoltaic fields of several megavolts per centimeter, the largest ever measured for any material.

Bandgap evolution in nanographene assemblies [PDF]
Physical Chemistry Chemical Physics, 2021 Recently, cycloarene has been experimentally obtained in graphene-like self-assembled structures. Here, we provide the energy gap evolution in those self-assemblies with a general extrapolation to other molecules.

On the Suppression Band and Bandgap of Planar Electromagnetic Bandgap Structures [PDF]
International Journal of Antennas and Propagation, 2014 Electromagnetic bandgap structures are considered a viable solution for the problem of switching noise in printed circuit boards and packages. Less attention, however, has been given to whether or not the introduction of EBGs affects the EMI potential of the circuit to couple unwanted energy to neighboring layers or interconnects.

Photonic bandgap infrared spectrometer [PDF]
Applied Optics, 2010 We propose and demonstrate an infrared (IR) absorption spectrometer, made with a spatially variable photonic bandgap (PBG) structure, a blackbody source, and a simple IR detector, to identify the IR molecular fingerprints of analyte molecules. The PBG-based structure consists of thermally evaporated, IR transparent, high-refractive-index chalcogenide ...
