• half as much Ag as the MS-made sample MS_2_RT, with the highest EF among other MS-made samples, has an EF that is 1.3 times higher. However, a more significant EF increase is observed for SERS substrates made by PLD deposition on heated GaN platforms. The PLD_1_200 sample has an EF 4.4 times higher

We additionally investigated the influence of deposition process parameters on the morphology of the fabricated Pt/C catalysts. Structure

• . Parameters such as the sample temperature, oxygen partial pressure, and laser intensity during PLD need to be optimized for each sample. Since our UHV NC-AFM is optimized for atomic resolution measurements, scanning over a wide range cannot be performed. To find suitable conditions for efficient PLD

• deposition, a deposited sample was taken out into the ambient atmosphere and its topography was measured with a tapping AFM in air. Although it is difficult to obtain atomic resolution images in tapping mode, the larger scanning area of tapping AFM enabled us to check whether a step-and-terrace surface was

• for application. In the present paper, we report the results on the fabrication of Au nanostructures by PLD in open air. The influence of the PLD deposition geometry on the surface morphology and physical properties of the samples was studied. The structures formed are columns comprised of an ensemble
