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 ...

Comparisons of methods for predicting composite roughness in ice-covered rivers
Shui kexue jinzhan, 2018 Composite roughness is a vital input parameter for hydraulic calculations of ice-covered channels. Two general equations for deriving composite roughness coefficient in ice-covered streams, based on the principles of flow continuity or force balance, are

Two constructions with parabolic geometries
, 2005 This is an expanded version of a series of lectures delivered at the 25th Winter School ``Geometry and Physics'' in Srni. After a short introduction to Cartan geometries and parabolic geometries, we give a detailed description of the equivalence between parabolic geometries and underlying geometric structures. The second part of the paper is devoted to

Rare‐Earth Yttrium Doping Advances High‐Performance AgSbTe2 Thermoelectrics
Advanced Energy Materials, EarlyView.Y‐doped AgSbTe2 achieves band and microstructure co‐optimization, with coherent Y‐Ag2Te interfaces enhancing phonon scattering and reducing lattice thermal conductivity to 0.26 W m−1 K−1. Combined with valence‐band broadening and increased carrier concentration, this yields ZT ≈ 2 at 623 K, average ZT = 1.5, and 7.3 % conversion efficiency of a single ...

Advanced Energy Materials, EarlyView.An alcohol‐adduct‐mediated strategy is employed to stabilize tin isopropoxide for the formation of a homogeneous double electron transport layer (ETL) incorporating SnO2 nanoparticles (NPs). This double‐ETL exhibits improved optical and charge‐transport properties due to reduced defect density and better energy level alignment, resulting in high ...
