The diodes were fabricated by applying the SAM molecule 4 '-[(3-methylphenyl)(phenyl) amino]biphenyl-4-carboxylic acid (CT21) onto titanium dioxide (TiO2) synthesized via the sol-gel method. The key parameters, including the ideality factor (n), series resistance (Rs), and barrier height (& empty;b), were used to assess the impact of CT21 on diode performance. Experimental results revealed that using CT21 at the TiO2/Al interface significantly enhances diode performance. The n decreased from 3.8 in the control diode to 1.9 with CT21. Rs was substantially reduced, and the & empty;b increased. The rectification ratio improved from 1x104 in the control diode to 1.1x105 in the CT21-modified diode. These enhancements, due to the CT21 molecule's ability to reduce interface states (Nss) and improve surface properties, underscore the potential of SAM coatings to open a new window in nanoelectronics with better performance and reliability.en10.1016/j.physb.2024.416686info:eu-repo/semantics/closedAccessDensity of statesInterface passivationSAMsSchottky diodeSeries resistanceTiO2Article696Nov16WOS:0013539510000012-s2.0-85208194567Q2Q2
