A groundbreaking study published in Advanced Functional Materials on February 16, 2025, unveiled a novel MXene thin film protected by reduced graphene oxide (rGO), termed rGM. This innovative film boasts exceptional charge transfer capabilities and the remarkable ability to stay stable in the ambient air. The protective rGO layer effectively shields the conducting layer of MXene from air oxidation, significantly enhancing air stability. After 40 days of exposure to air at 25°C and 40% relative humidity, the membrane resistance of the rGM film (135.9±2.3Ω/sq - 312.6±4.5Ω/sq) showed negligible amplification compared to the pure MXene film (145.0±2.3Ω/sq - 2,152.8±6.8Ω/sq).

With the development of integrated circuit (IC) technology, the scaling of silicon-based metal oxide semiconductor (MOS) field-effect transistors (FETs) is approaching their fundamental physical limits. Carbon nanotubes (CNTs) are considered promising materials in the post silicon era due to their atomic thickness and unique electrical properties, with the potential to improve transistor performance while reducing power consumption. High purity aligned carbon nanotubes (A-CNT) are an ideal choice for driving advanced ICs due to their high current density. However, when the channel length (Lch) decreases below 30nm, the performance of single gate (SG) A-CNT FET significantly decreases, mainly manifested as deteriorating switching characteristics and increased leakage current. This article aims to reveal the mechanism of performance degradation in A-CNT FET through theoretical and experimental research, and propose solutions.

A particle refers to the smallest independent and discrete unit formed by the nucleation and growth of substances in a specific reaction system (such as combustion, precipitation, gas-phase synthesis, etc.), with regular or irregular geometric shapes. It can be understood as the most fundamental individual that is "innate" in the process of material formation.

​The difference in cohesive force between different powders is due to the type and strength of interparticle forces (van der Waals forces, capillary forces, electrostatic forces, etc.), and its core influencing factors include particle size, surface roughness, moisture content, and material properties, resulting in cohesive force that can span multiple orders of magnitude (from 10 ⁻⁶ N to 10 ⁻¹ N). This difference can be quantitatively described through the aggregation feature index, surface tension, and roughness correction model.
