The Need As digital infrastructure scales and cyber threats become more sophisticated, the integrity of cryptographic systems increasingly depends on the quality of their randomness. From encryption keys to authentication protocols, weak or predictable entropy can undermine even the most advanced …

2D van der Waals (vdW) materials are atomically thin sheets that can be stacked to form heterostructures with customizable electronic, optical, and magnetic properties. These heterostructures are promising for next‑generation technologies such as quantum devices, optoelectronics, and spintronics…
