Extended Data Fig. 7: Work function changes.
From: Controlled growth of ordered monolayers of N-heterocyclic carbenes on silicon

a, Measured secondary electron onsets for the clean Si(111)-B surface (green), for the ordered \(2\sqrt{3}\times 2\sqrt{3}\) IPr monolayer (black), and for the IMe monolayer (red). The dashed grey lines show linear fits to the data used to determine the secondary electron onsets. b, Calculated work functions and c, work function changes as a function of NHC coverage.
