“…Such a rapid increase of the work function on surfaces with localized areas in the atmospheric-pressure dry processes has not been reported so far, although our previous report indicated the treatment's localized effect. 5) The ionization potential, shown in Fig. 3, increased in a similar manner with a similar increase rate, confirming that clear changes took place on the surfaces of the ITO films.…”

A fabric-type electrode has a two-dimensional plane structure around which atmosphericpressure plasmas are generated.…”

“…Such filter-like functions of various atmospheric-pressure (micro)plasma layers have been proposed for material synthesis. [9][10][11][12][13] We set indium tin oxide (ITO) thin films in the downstream region of the gas flow and observed the increase of the work function, 5) in which OH or other radicals are key species for its increase. However, we neither examined the details of the parameter dependences nor investigated the effects of the work function enhancement for applications of electronic devices.…”

The surface electronic properties of metal oxides, which affect the performances of layered electronic devices, are controlled by non-thermal atmospheric-pressure plasmas generated using a fabric-type electrode and gas flow induced through this plasma layer. We specify a method to control the work function of indium tin oxide (ITO) films by this plasma, in which such reactive species as oxidant radicals are generated. These oxidants are spatially transported in the gas flow to the ITO surface and increase the ITO’s work function, as verified in our experimental results. To examine the effects of the increased work function in a specific electronic device, we treat the surface of an ITO electrode in an organic light-emitting diode and observe the enhancement of the light-emitting efficiency.

Weakly ionized plasmas at or near 1 atm pressure, or atmospheric-pressure plasmas, have received increasing attention due to their scientific significance and potential for use in a variety of applications, particularly for medicine, agriculture, and food. However, there is a large imbalance between scientific research on plasma physics and applications, which is partly due to the considerable differences in the characteristics of these plasmas compared with those of low-pressure plasmas. This discrepancy is particularly related to the difficulty in performing plasma diagnostics for highly collisional plasmas. Information on electrons (such as the electron density and temperature) is essential since electrons play a dominant role in the generation of active species related to the physical and chemical processes inside the plasma. So far, limited diagnostics have been available for electrons such as Thomson scattering and optical emission diagnostics based on equilibrium models. Here, we review the available diagnostic methods along with their merits and limitations for characterizing electrons in weakly ionized collisional plasmas. Particular attention is paid to continuum radiation-based spectroscopy, which facilitates multidimensional imaging of electron density and temperature. The future impact of these plasmas on relevant fields (i.e. laboratory and industrial plasmas and their applications) is also addressed.
