The deposition of a metal oxide layer with good dielectric properties is a critical step in fabricating the gate dielectric of transistors based on two-dimensional semiconductors. However, current techniques for depositing ultrathin metal oxide layers on two-dimensional semiconductors suffer from quality issues that can compromise transistor performance. Here, we show that an ultrathin and uniform native oxide of gallium (Ga₂O₃) that naturally forms on the surface of liquid metals in an ambient environment can be prepared on the surface of molybdenum disulfide (MoS₂) by squeeze-printing and surface-tension-driven methods. The Ga₂O₃ layer possesses a high dielectric constant of around 30 and equivalent oxide thickness of around 0.4 nm. Due to the good dielectric properties and van der Waals integration, MoS₂ transistors with Ga₂O₃ gate dielectrics exhibit a subthreshold swing down to 60 mV dec⁻¹, an on/off ratio of 10⁸ and a gate leakage down to around 4 × 10⁻⁷ A cm⁻².

沉积具有良好介电特性的金属氧化物层是制造基于二维半导体的晶体管栅极介电质的关键步骤。然而，目前在二维半导体上沉积超薄金属氧化物层的技术存在质量问题，可能会影响晶体管的性能。在这里，我们通过挤压打印和表面张力驱动方法，在二硫化钼（MoS2）表面制备出超薄、均匀的原生氧化镓（Ga2O3），这种氧化物在环境中自然形成于液态金属表面。Ga2O3 层具有约 30 的高介电常数和约 0.4 纳米的等效氧化物厚度。由于良好的介电性能和范德华积分，带有 Ga2O3 栅极电介质的 MoS2 晶体管的阈下摆幅低至 60 mV dec-1，导通/关断比为 108，栅极漏电流低至约 4 × 10-7 A cm-2。

The human auditory system has a limited ability to perceive distance and distinguish speakers in crowded settings. A headset technology that can create a sound bubble in which all speakers within the bubble are audible but speakers and noise outside the bubble are suppressed could augment human hearing. However, developing such technology is challenging. Here, we report an intelligent headset system capable of creating sound bubbles. The system is based on real-time neural networks that use acoustic data from up to six microphones integrated into noise-cancelling headsets and are run on the device, processing 8 ms audio chunks in 6.36 ms on an embedded central processing unit. Our neural networks can generate sound bubbles with programmable radii between 1 m and 2 m, and with output signals that reduce the intensity of sounds outside the bubble by 49 dB. With previously unseen environments and wearers, our system can focus on up to two speakers within the bubble, with one to two interfering speakers and noise outside the bubble. An intelligent headset system that uses real-time neural networks run on an embedded central processing unit can create sound bubbles that selectively isolate groups of users from outside sounds.

在拥挤的环境中，人类听觉系统感知距离和分辨扬声器的能力有限。一种耳机技术可以产生一个声音气泡，气泡内的所有扬声器都可以听到，而气泡外的扬声器和噪音则被抑制，这种技术可以增强人类的听力。然而，开发这种技术具有挑战性。在此，我们报告了一种能够产生声泡的智能耳机系统。该系统基于实时神经网络，使用集成在降噪耳机中多达六个麦克风的声学数据，并在设备上运行，在嵌入式中央处理单元上以 6.36 毫秒的时间处理 8 毫秒的音频块。我们的神经网络可以生成半径在 1 米至 2 米之间的可编程声泡，其输出信号可将声泡外的声音强度降低 49 分贝。对于以前未见过的环境和佩戴者，我们的系统可以聚焦于气泡内最多两个扬声器，以及气泡外一到两个干扰扬声器和噪音。
