EC-STM, SECPM and CV of Rh(111): (A) In situ EC-STM (500 nm × 500 nm, hmax = 10 nm) US = 500mV vs. NHE, (B) SECPM (200 nm × 200 nm, hmax = 4 nm) and image of Rh(111) in 0.1 M HClO4 at US = 500 mV vs. NHE (C) CVs obtained in 0.1 M HClO4 (black curve) and 1 M H2SO4 (red curve) with a scan rate of 100 mVs-1. Imaging conditions: STM: IT = 1 nA, Ubias = 100 mV, SECPM: ∆U = 5 mV.
