Nanocone Fabrication: The truncated nanocone structures were fabricated using HCL.17 As substrates, circular glass slides (Menzel Gläser) with a diameter of 25 mm and a thickness of 0.2 mm were used. The deposition of the nanocone materials for the Pd experiments was carried out in electron beam evaporator (AVAC HVC600) with a water-cooled sample holder at a base pressure of 2 × 10−6 mbar and an evaporation rate of 3 Å s−1 for Au, 0.5 Å s−1 for SiO2, and 1 Å s−1 for Pd. The deposition of the nanocone materials for the Mg experiments was carried out in an ultrahigh vacuum (UHV) electron beam evaporator (APX Scientific Instruments) at a base pressure of 2 × 10−8 mbar using an evaporation rate of 2 Å s−1 for Au, 1 Å s−1 for Ti, 0.5 Å s−1 for Mg, and 1 Å s−1 for Pd.
