Fig. 2: Gate-controlled resistance response of Broad-spectrum C-2DEG Gas Sensor.
From: A broad-spectrum gas sensor based on correlated two-dimensional electron gas
a Unique back gating drives non-volatile MIT, resulting in greatly enhanced gas sensitivity in different gas environments, e.g. N2 (purple), O2 (yellow), C2H4 (red), and CO2 (blue). b Responses in a simulated Martian atmospheric environment (95% CO2 + 3% N2 + 2% CO, 4.5 torr measured at 300 K). c The curve of resistance (red left axis) and its first order differential (blue right axis) with temperature in 10 torr O2 (measured at 300 K) atmosphere. Source data are provided as a Source Data file.
