Contact Potential Difference of ZnO Layer Adsorbing p-Type Dye and n-Type Dye

In-situ drug synthesis at cancer cells for molecular targeted therapy by molecular layer deposition - conceptual proposal

“…When p-type molecules are adsorbed onto the ZnO layer, as shown in Figure 15, the surface potential becomes more negative. This is attributed to the additional negative electric dipole moments generated by the negative charge in the p-type molecules on the ZnO surface [29]. Conversely, when n-type molecules are adsorbed onto the ZnO layer, the surface potential becomes less negative.…”

“…Conversely, when n-type molecules are adsorbed onto the ZnO layer, the surface potential becomes less negative. This is attributed to the positive charge in the n-type molecules on the ZnO surface [29].…”

“…This is caused by the positive charge in the n-type molecules on the top of the stacked structure [29]. For the three-molecule stacked structure of ZnO/RB/CV/EO, the surface potential becomes more negative compared to the surface potential of the plain ZnO.…”

“…When p-type dye molecules are adsorbed on the ZnO layer, as shown in Figure 8.22, the surface potential becomes more negative. This is attributed to the additional electric dipole moments generated by the negative charge in the p-type dye molecules on the ZnO surface [42]. Conversely, when n-type dye molecules are adsorbed on the ZnO layer, the surface potential becomes less negative due to the positive charge in the n-type dye molecules [42].…”

“…This is caused by the positive charge in the n-type dye molecules on the top of the stacked structure [42]. providing RB, CV, and EO sequentially, and [ZnO/RB/CV/FL], which was fabricated by providing RB, CV, and FL sequentially, the surface potential becomes more negative compared to that for undyed ZnO.…”
