一般描述

Graphene preparation method: electrochemical exfoliation.
Graphene thickness by AFM: 80%, 1-3 layers.
Sheet size by AFM: Few micrometers
Oxygen content: 7.5% (by XPS) (C/O-ratio: 12.3).
Raman I_D/I_G ratio: 0.4.
Sheet resistance: 4.8 kΩ/sq.
Typical properties of films produced thereof (after dry transfer from PTFE-filter):

15 nm film: 85% transmittance, sheet resistance of 16 kΩ/sq (as made), 4.1 kΩ/sq (after 30 min, 200 °C), <1 kΩ/sq (conc. HNO₃-treatment).
25 nm film: 73% transmittance, sheet resistance of 8 kΩ/sq (as made), 2.4 kΩ/sq (after 30 min, 200 °C), <1 kΩ/sq (conc. HNO₃-treatment).
