In order to improve performance of soar cell, increase of lifetime of carriers is considerd very important. Lifetime of carrier may be different in each particle, and observing individual particle could give us important information for increasing carrier lifetime. Vacuum level is one of important properties influencing carrier lifetime, and we are trying to observe vacuum level of individual particles. Here is our first report of vacuum level of Au-TiO2 NP systme.
