| ABSTRACT |
|
For the ultimate purpose of mapping, with a high precision, the local electrochemical potentials of an ionic carrier in nonisothermal conditions, an ionic probe for Ag+ ions, Pt/Ag/AgI, has been miniaturized to a tip size of 20∼30$mutextrm{m}$, by an electrochemical technique combined with gas (I2)/solid (Ag) reaction, and its performance checked by measuring the partial electronic and ionic conductivities of Ag2S from the ion and electron blocking cells, Ag/Ag2S/Pt and Ag/Ag2S/AgI/Ag, respectively. The results have firmly confirmed that the miniaturzed probe function quite validly and be very promising. |
