Nature Communications | ZEPTOOLS ZEM Series Desktop Scanning Electron Microscope Aids Development of Highly Stable Fiber-Integrated Graphene Ultrafast Electron Source

In the field of vacuum electronics, stable and durable ultrafast electron sources are critical for achieving high-precision time-resolved imaging and spectroscopic analysis. Traditional electron sources typically rely on metals such as gold and tungsten, or low-dimensional materials such as carbon nanotubes, as photocathodes, generating electron pulses through mechanisms such as multiphoton emission, the photoelectric effect, or optical field emission. However, these methods have significant limitations. On the one hand, multiphoton emission and optical field emission require ultra-high-power lasers or deep ultraviolet pulse excitation, leading not only to cathode material damage and mechanical vibration but also demanding extreme vacuum conditions. On the other hand, existing electron sources generally suffer from time-dependent beam current instability, requiring recalibration every 4–6 hours, which severely constrains equipment operational efficiency and data reliability.

Nature Communications | ZEPTOOLS In-Situ TEM Facilitates Research on Chip-Scale Compact Photonic Random Neurons

With the advent of the big data era, traditional artificial intelligence hardware systems based on complementary metal-oxide-semiconductor (CMOS) technology and the von Neumann architecture are severely constrained by the physical limits of Moore's Law when facing exponentially growing computational demands, encountering significant challenges such as bottlenecks in computational efficiency improvement and high energy consumption. Consequently, integrated photonic neural networks (PNNs), leveraging the inherent advantages of photons—ultra-high speed, wide bandwidth, high parallelism, and low power consumption—have emerged as a highly promising new computing paradigm that integrates neuromorphic and photonic computing. In biology, neurons do not perform deterministic calculations; internal noise, such as the stochastic opening of their ion channels, endows biological neurons with inherent stochastic dynamics, thereby providing crucial support for probabilistic computations like Bayesian inference. Therefore, introducing probabilistic models into photonic hardware is of great significance for suppressing the overconfidence of deterministic reasoning and enhancing the accuracy and robustness of neural networks.

ZEPTOOLS | In-Situ Sample Holder: Equipping Transmission Electron Microscopes with a Pair of “Movable Hands”

If you’re familiar with transmission electron microscopy, you probably know that it can capture the microscopic world at the atomic scale with remarkable clarity. But what you may not realize is that for a long time, TEM could only image “static” samples—much like using a camera to take an ID photo of a nail: the image faithfully reflects whatever state the nail was in at the moment of exposure. When researchers want to observe what happens when that nail is heated, stretched, or subjected to an electric current, they typically have to rely on comparing before-and-after images to infer the intermediate processes. This approach is akin to watching a movie but being able to see only the beginning and the end.
