About Millicoulombs per square centimetre

The millicoulomb per square centimetre (mC/cm²) equals exactly 10 C/m², used in electrochemical plating and electrophoretic deposition. Electrodeposition of copper at 10 C/m² deposits a monolayer-scale film; faradaic charge density in electrochemical supercapacitors is 1-100 mC/cm²; silver electroplating baths run at 2-10 mC/cm² for thin coatings. 1 mC/cm² = 10 C/m².

About Attocoulombs per square metre

The attocoulomb per square metre (aC/m²) equals 10⁻¹⁸ C/m², the scale for areal charge density on individual molecular monolayers measured by Kelvin probe force microscopy. A single elementary charge on a 1 µm² area gives about 0.16 aC/m²; contact potential distributions in organic photovoltaic blends correspond to aC/m²-scale surface charge. 1 aC/m² = 10⁻¹⁸ C/m² = 10⁻³ fC/m².
