- Introduces fluorographane (CF) as a non-volatile memory architecture exploiting covalent fluorine orientation for binary storage.
- C-F inversion barrier of ~4.6 eV ensures extreme stability with negligible thermal or quantum tunneling bit-flip rates at 300 K.
- Achieves 447 TB of storage per square centimeter without retention energy, with volumetric nanotape architectures reaching up to 9 ZB/cm³.
- Outlines a tiered read-write system from scanning-probe to dual-face parallel configurations, projecting 25 PB/s throughput.
- Prototype demonstrates areal density surpassing existing technologies by over five orders of magnitude.
