NPL – the National Physical Laboratory – has developed a unique system allows transport measurements under highly-controlled environments, enabling environmentally specific graphene characterisation.

In summary, this system offers the following services:

• Magneto-transport measurements of patterned and un-patterned samples;
• Operation in ambient and vacuum (P≈10^-7 mbar) conditions;
• Four gases dilution down to 5 ppb;
• Humidity ranges 0–90%;
• Heating stage (30–200 °C);
• Long-time measurements; fm 2016 son crack
• Graphene film electrical characterisation for quality control.
