Goal
Enable mask-less, 3-D atomic-scale printing and additive manufacturing at wafer scale with sub-nanometer feature sizes.
Problem
Current nanofabrication techniques (e.g., electron-beam lithography) are limited by mask requirements, resolution >0.2 nm, and low throughput.
Concept Summary
A coherent matter-wave beam is generated by synchronizing multiple low-energy charged-particle emitters using the Aharonov-Bohm effect (phase change without energy exchange) and Kuramoto-type coupled-oscillator synchronization via mutual inductance of superconducting loops. The resulting beam maintains phase coherence across the manufacturing zone, allowing atomic-scale patterning, deposition, and assembly without masks.
Principles
- Aharonov-Bohm phase control
- Kuramoto synchronization of coupled oscillators
- Superconducting loop mutual inductance
- Bose-Einstein condensate-like coherence
- Artificial gauge field manipulation
