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.

Application Strategy of Drainage Gas Production Technology in Shallow Gas Fields

E3S Web of Conferences, 2023
During the use of gas wells, the production time must be increasing. If reasonable measures are not taken for a long time, the bottom hole pressure will be reduced. If the gas flow in the gas well can no longer drive the water at the bottom to the ground, it will lead to the accumulation of water at the bottom of the well and produce back pressure ...
