Ferroelectric Polarization Enabled Threshold Voltage Modulation in High Electron Mobility Transistor

Advanced Functional Materials, EarlyView.
A comprehensive model is developed to capture the coupled electrostatics of a ferroelectric capacitor and a metal‐insulator‐semiconductor high electron mobility transistor (MISHEMT) connected in ferroelectric‐metal high electron mobility transistor (FeMHEMT) configuration.

Functionalizing Micro‐to‐Mesoscopic Electrode Architectures for Regulating Electron Transfer Behaviors in Electrocatalysis

Advanced Functional Materials, EarlyView.
A systematic review is conducted to assess the influence of electrode architecture across micro‐ to mesoscopic length scales on electron‐transfer pathways in electrocatalysis. We discuss the structure‐activity relationships in electrocatalytic applications, including resource recovery and environmental remediation, and provide cost‐effective, efficient

Tunable Complementary Doping Strategy Enables High‐Performance Homo‐Channel CMOS in Monolayer WSe2

Advanced Functional Materials, EarlyView.
Polarity‐selective modulation enables a homo‐channel WSe2 CMOS platform from a single 2D semiconductor. MoOx and AlN tune WSe2 toward p‐ and n‐type operation, respectively, yielding complementary FETs and inverters with balanced switching, high voltage gain, low static power, and promising scalability for 2D logic integration.

High-pressure gas as a dielectric

Electrical Engineering, 1941
Impulse and 60-cycle breakdown strength of sphere gaps, rod gaps, and of samples built up of solid and fluid dielectrics are reported. The tests were made in nitrogen up to 200 pounds per square inch gauge pressure and in Freon up to 70 pounds per square inch gauge pressure. Dielectric strength values were compared with the breakdown of transformer oil

ABANDONMENT PRESSURE OF GAS WELLS

Proceedings of Petroleum Economics and Valuation Symposium, 1962
1962 Economics and Valuation Symposium, Dallas, March 15–16, 1962 When I accepted the invitation to talk on abandonment pressures of natural gas fields I thought the task would be that of consulting various easily-found records, abstracting such data as I thought to bear on the subject, presenting it along with a few apposite ...

Gas-pressure and pressure-stratification in the sunspot

Solar Physics, 1969
By a curve of growth analysis, using photospheric and umbral equivalent widths, published by Fricke and Elsasser, and absolute oscillator-strengths, it has been found, that the gas pressure in a sunspot is lower than in the corresponding layers of the photosphere.

A Pressure Regulator for Proportional Regulation of Two Gas Pressures

IEEE Transactions on Biomedical Engineering, 1978
A pressure regulator which maintains a constant ratio of pressures at two gas outlets is described. The device consists of three chambers, a central reference chamber; and two side chambers, each one separated from the central one by a double diaphragm. The two double diaphragms are connected to two valves that control the respective gas flows into the
