Power dissipation is a fundamental issue for future chip-based electronics. As promising channel materials, two-dimensional semiconductors show excellent capabilities of scaling dimensions and reducing off-state currents. However, field-effect transistors based on materials are still confronted with the thermionic limitation subthreshold swing 60 mV decade-1 at room temperature. Here, we present an atomic threshold-switching transistor constructed by integrating metal filamentary threshold...
Abstract Optical physical unclonable functions (PUFs) have been proven to be one of the most effective anti‐counterfeiting strategies. However, optical PUFs endowed with flexibility and biocompatibility not developed, limiting their application scenarios. Herein, biocompatible flexible PUF labels are developed by randomly embedding microdiamonds in silk fibroin films. The can conformally attached onto surface complex shaped objects, providing desired protection against fake interior...
Flexible electronics is a cutting-edge field that has paved the way for artificial tactile systems mimic biological functions of sensing mechanical stimuli. These have an immense potential to enhance human-machine interactions (HMIs). However, still faces formidable challenges in delivering precise and nuanced feedback, such as achieving high sensitivity emulate human touch, coping with environmental variability, devising algorithms can effectively interpret data meaningful diverse contexts....
Many narrow band-gap semiconductors cannot fulfil the energetic requirements for water splitting, thus assistance of large external voltages to complete decomposition reaction is required. Through thermal Fe(NO3)3 on n-Si nanowires prepared by chemical etching method, we fabricated a high-performance n-Si/α-Fe2O3 core/shell nanowire array photoanode that exhibited low photocurrent onset potential 0.5 V vs. RHE and high 5.28 mA cm(-2) at 1.23 RHE, under simulated AM 1.5G irradiation. The...
n-ZnO nanofilm/p-Si micropillar heterostructure light-emitting diode (LED) arrays for white light emissions are achieved and the emission intensity of LED array is enhanced by 120% under -0.05% compressive strains. These results indicate a promising approach to fabricate Si-based components with high performances piezo-phototronic effect, potential applications in touchpad technology, personalized signatures, smart skin, silicon-based photonic integrated circuits.
Based on white light emission at silicon (Si)/ZnO hetrerojunction, a pressure-sensitive Si/ZnO nanowires heterostructure matrix emitting diode (LED) array is developed. The intensity of single LED tuned by external strain: when the applied stress keeps increasing, first increases and then decreases with maximum value compressive strain 0.15–0.2%. This result attributed to piezo-phototronic effect, which can efficiently modulate utilizing strain-induced piezo-polarization charges. It could...

Cytoplasmic viscosity (μc) is a key biomechanical parameter for evaluating the status of cellular cytoskeletons. Previous studies focused on white blood cells, but data cytoplasmic tumour cells were missing. Tumour (H1299, A549 and drug-treated H1299 with compromised cytoskeletons) aspirated continuously through micropipette at pressure -10 or -5 kPa where aspiration lengths as function time obtained translated to based theoretical Newtonian fluid model. Quartile coefficients dispersion...

The extracted binary codes from PUFs are random, unclonable, robust enough for applications in entity authentication encrypted communication.
This paper reports a hybrid nanoantenna consisting of an inner metal nanodisk and outer dielectric ring cavity with superior fluorescence enhancement performance. Based on the multipole decomposition analysis coupled oscillator model, it is found that surface plasmon resonance could interact magnetic dipole mode more strongly than electric mode, improving excitation rate in gap region by 1 order magnitude compared to those from pure or constituent. The structure partially inherits low loss...

Bamboo‐like gallium nitride (GaN) microwires are synthesized via chemical vapor deposition (CVD) to fabricate piezotronic memristors. Defect boundary areas (DBAs) near the bamboo knots produce apparent switching between high and low resistance states upon sweeping of magnitudes biased voltages across GaN microwire‐based devices at room temperature. Furthermore, by coupling piezoelectric semiconducting properties in microwire, effect is introduced effectively modulate SET strain‐induced...
