Uncovering Hidden Quantum Landscapes

Scientists at the Weizmann Institute have unveiled the Atomic Single Electron Transistor (Atomic SET), a scanning microscope that uses a single atom as a quantum sensor. The device achieves roughly one‑nanometer spatial resolution—about 100 × better than existing probes—and can detect electrostatic potential changes as small as one‑part‑million of a single‑electron charge. Using the Atomic SET, the team mapped the energy landscape of a graphene/hexagonal‑boron‑nitride moiré superlattice and found potentials nearly twice as strong as theoretical predictions. The breakthrough promises direct visualization of hidden quantum fields that drive exotic material behavior.
