Controllable selenization kinetics via stabilizing Se concentration enables 14.33% CZTSSe solar cells
The early-stage uniformity and stability of selenium (Se) vapor during selenization critically determine the power conversion efficiency (PCE) of Cu2ZnSn(S,Se)4 (CZTSSe) devices. However, traditional...
Nano-Raman imaging of monolayer MoS2 nanoribbons
Two-dimensional semiconductors are promising candidates for next-generation electronics. However, characterizing these materials at technologically relevant dimensions remains underexplored. Here, we...
An ultrahigh stretchable wearable self-powered hydrogel sensor driven by body heat
Flexible wearable hydrogel sensing devices have attracted significant attention in recent years. However, the integration of high stretchability, body heat-driven self-powering capabilities, and effec...
FM and double modulation interferometry with sub-nanometer resolution using the iLens technique
We report a modulation technique applicable to optical two-beam interferometers with unequal arm lengths that allows for highly precise, low-noise displacement measurements below the nanometer regime...
Supervised cryo-EM tomography denoising enabled by physics-based image simulation
Cryo-electron tomography enables three-dimensional visualization of biomolecules in their native aqueous state but suffers from low signal-to-noise ratio (SNR) due to electron dose limitations. Subtom...
Altermagnetic-RuO2-based all-magnetic tunnel junction: Giant and multistate tunneling magnetoresistances with perfect spin filtering
Altermagnets generate momentum-dependent spin-polarized currents without net magnetization, offering an intriguing platform for spintronic applications. However, altermagnet-based tunneling devices of...
Field-free SOT switching in Pd/PdCo bilayers with a vertical gradient induced by rapid thermal annealing
Achieving field-free magnetization switching in spin–orbit torque (SOT) devices is essential for practical spintronic applications. While recent studies have proposed strategies involving complex mult...
Observation of two-dimensional hole gas distribution and transport in GaN composite p-channel at cryogenic temperatures
The density of two-dimensional hole gas (2DHG) in gallium nitride (GaN)-based heterojunctions with strong polarization effects is generally considered to be temperature-independent. In this work, we o...
Recoverable ultrathin Hf0.5Zr0.5O2-based ferroelectric tunnel junction
Here, we report a ferroelectric tunnel junction (FTJ) based on ultrathin Hf0.5Zr0.5O2 (HZO) that can be electrically recovered from memory fatigue to reach significantly prolongated endurance. A high...
Damage-free sputtered ITO top electrode for semi-transparent organic solar cells: Protective and electronic role of the MoO3 transport layer
We report on the integration of a sputtered indium tin oxide transparent top electrode for semi-transparent organic solar cells (ST-OSCs). To mitigate sputtering-induced damage to the underlying organ...
