• /HOPG sample, ≈45 nm of Au was deposited on ≈5 nm of Ti by evaporation on top of a freshly cleaved HOPG surface. For the Au/SiO2 sample, ≈50 nm of Au was deposited by evaporation on the SiO2 surface. During measurements all samples were mounted on a conductive surface using silver paint which was at

• were made by applying a potential of 1 V at the sample: 20 s in darkness, 50 s under illumination and another 50 s in darkness. For this, two rectangular metallic contacts (0.5 × 0.2 cm) were painted on the surface of the films with silver paint in a square sample of 0.5 cm2. Energy dispersive X-ray

• Digital Instruments Nanoscope III (Digital Instruments, Santa Barbara, California). For the preparation of the STM tips, a Pt/Ir wire (80/20) was etched in 4.5 M NaCN and coated with an electrophoretic paint to reduce Faradic currents at the tip/electrolyte interfaces below 50 pA.

• thus considered to be hydrophobic. To apply the voltage to the system, the sample was glued to a metal sample plate with conductive silver paint, in this case, the silicon substrate and the sample metal plate were electrically connected and the voltage could be applied. The metal sample plate was used

• contact line moves, the minimum value of the CA was recorded as the receding CA. The CAH was calculated as well. The whole experimental process was limited to 10 min in order to minimize the effect of evaporation. In the experimental setup, there are several layers such as silver paint, silicon, PS

While the focus has been on identifying nonidealities without providing simple or complete solutions, the objective is not to paint a bleak picture of the technique, but rather to raise awareness of open research

• MWCNTs form a quasi-continuous film, which creates the photoactive Schottky heterojunction with the Si. The top electrodes were made of silver paint, while the rear contact was sputtered aluminium. The photocurrent spectra were measured by using an optical setup comprising a xenon lamp equipped with a

• photovoltaic device. The Schottky junction between the Si and the MWCNT film is the photoactive junction. Steps of SiO2 (300 nm) are used to avoid a short-circuit forming between the silver paint (top electrode) and the silicon substrate. The back contact is made of aluminium. In the in-plane geometry, the
