“…There is therefore significant room for improvement in sensitivity by utilizing more sophisticated SERS substrates. 17 The Raman spectra for PPA over 1 h confirms the stable chemisorption of PPA on the alumina surface at 3.7 Torr and room temperature (Supporting Information Figure 1). Figure 2a presents the Stokes and anti-Stokes peaks for PPA on alumina using the SERS substrate.…”

Low-temperature, nonthermal plasmas generate a complex environment even when operated in nonreactive gases. Plasma-produced species impinge on exposed surfaces, and their thermalization is highly localized at the surface. Here we present a Raman thermometry approach to quantifying the resulting degree of surface heating. A nanostructured silver substrate is used to enhance the Raman signal and make it easily distinguishable from the background radiation from the plasma. Phenyl phosphonic acid is used as a molecular probe. Even under moderate plasma power and density, we measure a significant degree of vibrational excitation for the phenyl group, corresponding to an increase in surface temperature of ∼80 °C at a plasma density of 2 × 10 10 cm −3 . This work confirms that surface-localized thermal effects can be quantified in low-temperature plasma processes. Their characterization is needed to improve our understanding of the plasmainduced activation of surface reactions, which is highly relevant for a broad range of plasma-driven processes.

“…Berrospe-Rodriguez et al recently used Raman thermometry to measure the thermal response of multilayer graphene on a copper substrate during plasma exposure. Like the thermoreflectance techniques employed by Walton et al and Tomko et al, the approach offers a noncontact spatially resolved technique to interrogate the temperature of a material.…”

“…However, with temporal resolution, the authors found a time frame during which the material surface was transiently cooled through plasma exposure; this effect had been "averaged-out" in earlier studies and is likely the result of photodesorption of adsorbed species due to photons created during the first tens of nanoseconds following plasma ignition. Berrospe-Rodriguez et al 59 recently used Raman thermometry to measure the thermal response of multilayer graphene on a copper substrate during plasma exposure. Like the thermoreflectance techniques employed by Walton et al 57 and Tomko et al, 58 the approach offers a noncontact spatially resolved technique to interrogate the temperature of a material.…”

“…Notably, nanoscale interactions that can be modified from surface chemistry, pressure, and phase changes in the liquid and gas must be considered to properly account for heat transfer, which we overview in Section . We end Section by describing recent studies on the energy transfer at solid surfaces exposed to plasma, − where this fourth phase of matter delivers a plethora of energy carriers to the solid and can give rise to different energy transfer processes as a function of time during plasma exposure, including the recent demonstration of “plasma cooling”, where a directed plasma jet can be used to transiently cool a surface.…”

Ultrafast and Nanoscale Energy Transduction Mechanisms and Coupled Thermal Transport across Interfaces

The coupled interactions among the fundamental carriers of charge, heat, and electromagnetic fields at interfaces and boundaries give rise to energetic processes that enable a wide array of technologies. The energy transduction among these coupled carriers results in thermal dissipation at these surfaces, often quantified by the thermal boundary resistance, thus driving the functionalities of the modern nanotechnologies that are continuing to provide transformational benefits in computing, communication, health care, clean energy, power recycling, sensing, and manufacturing, to name a few. It is the purpose of this Review to summarize recent works that have been reported on ultrafast and nanoscale energy transduction and heat transfer mechanisms across interfaces when different thermal carriers couple near or across interfaces. We review coupled heat transfer mechanisms at interfaces of solids, liquids, gasses, and plasmas that drive the resulting interfacial heat transfer and temperature gradients due to energy and momentum coupling among various combinations of electrons, vibrons, photons, polaritons (plasmon polaritons and phonon polaritons), and molecules. These interfacial thermal transport processes with coupled energy carriers involve relatively recent research, and thus, several opportunities exist to further develop these nascent fields, which we comment on throughout the course of this Review.

“…These free radicals, which are more reactive than molecules or atoms, can form graphene at lower temperatures. On the other hand, intense ion bombardment from dense plasma heat the substrate [80,81]. Free radicals generated by the plasma bind to surfaces exposed to the plasma, resulting in the release of heat and the increase of substrate temperature.…”

Graphene has received much attention in multiple fields due to its unique physical and electrical properties, especially in the microelectronic application. Nowadays, graphene can be catalytically produced on active substrates by chemical vapor deposition and then transferred to the target substrates. However, the widely used wet transfer technique often causes inevitable structural damage and surface contamination to the synthetic CVD graphene, thus hindering its application in high-performance devices. There have been numerous reviews on graphene growth and transfer techniques. Thus, this review is not intended to be comprehensive; instead, we focus on the advanced plasma treatment, which may play an important role in the quality improvement throughout the growth and transfer of graphene. Promising pathways for future applications are also provided.
