Transparent conducting oxides

UU perform research on transparent conducting oxides (TCO) and materials for optoelectronic device electrodes by modified reactive magnetron sputtering processes such as multilayer OMO structures (Fig. 3), and by combining nanopatterning (nanodots, nanorods, etc.) with TCO materials for making e.g. thermoelectric coatings.

Figure 3: 3 FE-TEM cross-sectional images of (a) Ag, (b) Ag-Pd-Cu (APC) alloy, (c) APC:O (Г = 3%) and (d) APC:O (Г = 10%) showing suppressed Ag agglomeration in the APC:O film structure. Г is the ratio of oxygen flow rate to the total flow rate during reactive magnetron sputtering. In collaboration with Song’s group at Pusan National University, Korea
