Electroless copper films are used in printed circuit board industry to establish a conductive layer on insulating substrates. These films may have failures (voids, blisters) related to stress and/or hydrogen co-deposition in Cu films. Typical methods to determine amount of hydrogen are destructive and indirect. We have developed a time-resolved method to measure amount of hydrogen released...

The way that water wets a surface can be controlled by manipulating surface energies and/or surface topography. Although these factors can be controlled very well on the lab scale for certain kinds of materials, it is very challenging to achieve good control on compositionally heterogeneous surfaces such as stainless steel. Here, we show that mildly alkaline electrolytes can be used to...

Invited Speaker / Conférencier(ère) invité(e)

Advances in THz generation have enabled a wide range of new scientific tools that probe previously inaccessible dynamics in materials. In the area of scanning tunneling microscopy the capability of generating large amplitude THz pulses have enabled practical ultrafast scanning tunneling microscopy experiments. In a THz-coupled scanning tunneling microscope (THz-STM), THz pulses couple to the...

Roll-annealed (RA) copper foils are commonly used in the printed circuit industry as flexible conductive base materials. The RA process produces foils with the crystallites aligned in particular directions. RA foils used in applications have either {100}<001> “cube” texture, or a mixture of {112}<111> “copper”, {123}<634> “s” and “cube” textures. Manufacturing circuits requires the...

The structure and properties of perovskite substrates have attracted substantial interest due to material’s popularity as a substrate for complex oxide epitaxy [1,2]. Strontium titanate (SrTiO3) is among the most popular perovskites, with film quality dependent on the structure of the substrate at the beginning of the growth process. Here, we examined the surface structure of SrTiO3 (100)...
