Physics‐Based Compact Modeling of Advanced 3D Nanoscale Vertical NAND Flash Memory

Advanced Electronic Materials, EarlyView.
For advanced 3D NAND flash memory, a unified compact model for SPICE is proposed that spans from the intrinsic unit cell to the full string and captures the electrostatic coupling with adjacent inhibit strings. It can successfully predict read behavior, program/erase dynamics, and interactions between neighboring cells, reflecting array‐level behavior ...

Electronic Structure Effects During Cooperative Phase Transitions in Organic Semiconductor Single Crystals

Advanced Electronic Materials, EarlyView.
A cooperative phase transition in the organic semiconductor ditBu‐BTBT crystal around 70°C reorganizes molecular structure and dynamics, altering its electronic properties. Soft x‐ray reflectivity and optical spectroscopy reveal shifts in electronic resonances and a widening of the optical bandgap. The transition reduces intermolecular interactions and

Sub-10 nm Scalability of Junctionless FETs Using a Ground Plane in High-K BOX: A Simulation Study

IEEE Access, 2020
The leakage mechanisms of inefficient volume depletion and lateral band to band tunneling (L-BTBT) restrict the scaling of SOI-junctionless (JL) FETs. Therefore, in this article, we investigate the scalability of the SOI-JLFETs by incorporating a ground ...

Molecular Design and Interfacial Functions of Self‐Assembled Monolayers for Perovskite and Tandem Solar Cells

Advanced Energy Materials, EarlyView.
We identify two decisive levers for SAM interfaces: molecular design (carboxylic acid‐based, phosphonic acid, other anchoring chemistries, and polymeric SAMs) and mixing routes (co‐assembly, in situ assembly, pre‐ and post‐treatment). Coordinated tuning of headgroups and assembly pathways optimises energy alignment and film formation, suppresses ...

Improving the Gate-Induced Drain Leakage and On-State Current of Fin-Like Thin Film Transistors with a Wide Drain

Applied Sciences, 2018
Polycrystalline silicon (poly-Si) thin film transistors (TFT) with a tri-gate fin-like structure and wide drain were designed and simulated to improve gate-induced drain leakage (GIDL), ON-state current, and breakdown voltage.
