| contents | Molecular adsorption is pivotal in device fabrication and material synthesis for quantum technology. However, elucidating the behavior of physisorption poses technical challenges. Here graphene with ultrahigh sensitivity was utilized to detect ozone adsorption at cryogenic temperatures. Significant hole doping observed in graphene indicates a strong interaction between ozone and graphene. Interestingly, the adsorption exhibits asymmetry with positive and negative gate voltages. The strong affinity of ozone provides a tool to modulate materials and devices, while the gate tunability of adsorption offers new insights into construction and manipulation of oxide quantum materials. |
