Electrical properties of the NLGE and the substrate.
| Initial glass wall | Conductive NLGE tip | Nanochannel | |
|---|---|---|---|
| Thickness[m] | 1000±50×10−9 | 180±50×10−9 | |
| Potential [V] | 10 | 6.5 (turn-on) | 3.5 |
| Conductivity [S/m] | ~10−14 | ~0.05† | 1.01 |
| Resistance [Ω] | ~1012 | 356×106 | 187×106 |
This is the averaged conductivity of the NLGE tip, which varies according to the radial position (see Supplementary 5.3). The low field conductivity of glass is from ref. 28.
