Analytical modeling of capacitances for GaN HEMTs, including parasitic components

, 2014
In this paper, a surface potential-based terminal charge and capacitance model, including parasitic components for AlGaN/GaN HEMTs is developed. First, by solving the charge control equations, the sheet charge density in the channel is modeled with a ...

Impact of Power Module Parasitic Capacitances on Medium Voltage SiC MOSFETs Switching Transients [PDF]

, 2020
Increased switching speeds of wide bandgap (WBG) semiconductors result in a significant magnitude of the displacement currents through power module parasitic capacitances that are inherent in packaging design.

Printed Integrated Logic Circuits Based on Chitosan‐Gated Organic Transistors for Future Edible Systems

Advanced Functional Materials, EarlyView.
Edible electronics needs integrated logic circuits for computation and control. This work presents a potentially edible printed chitosan‐gated transistor with a design optimized for integration in circuits. Its implementation in integrated logic gates and circuits operating at low voltage (0.7 V) is demonstrated, as well as the compatibility with an ...

Detailed Analysis of a Regenerative Active Clamping Snubber for a Phase-Shifted Converter

IEEE Access
The phase-shifted converter (PSFB) is one of the most used converters for applications where high power and galvanic isolation are required. To achieve zero voltage switching (ZVS) on the primary side these converters use the leakage inductance of the ...

Punch-Through-Stopper Free Nanosheet FETs With Crescent Inner-Spacer and Isolated Source/Drain

IEEE Access, 2019
Structural modifications of 5-nm node nanosheet FETs (NSFETs) were quantitatively analyzed using fully calibrated TCAD. The NSFETs with crescent inner spacer improve the short-channel effects by increasing effective gate lengths but also increase the ...

Composites of Shellac and Silver Nanowires as Flexible, Biobased, and Corrosion‐Resistant Transparent Conductive Electrodes

Advanced Functional Materials, EarlyView.
Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...

Simultaneous Enhancement of Performance and Stability in Dual‐Gate a‐IGZO Thin‐Film Transistors via Single‐Step Laser Annealing for Capacitor‐Less DRAM

Advanced Functional Materials, EarlyView.
A single‐step laser annealing strategy is presented for dual‐gate a‐IGZO TFTs. The steep thermal gradient induces graded oxygen doping in the channel and simultaneous WOx removal at the contacts, enabling concurrent interface and contact engineering.
