Transparent electrodes based on molybdenum-titanium-oxide with increased water stability for use as hole-transport/hole-injection components

Figure 6 from Selina Goetz et al. 2022 “Transparent electrodes based on molybdenum–titanium–oxide with increased water stability for use as hole-transport/hole-injection components”: AFM images of a bare glass, b bare PET, c MTO40/Ag14/MTO10/30 on glass and d MTO40/Ag14/MTO10/30 on PET Figure 6 displays the 1 × 1 µm2 AFM images of the DMD on glass and PET, as well as the corresponding bare substrate. The roughness of the electrodes is mostly affected by the underlying substrate. The extracted root mean square value (RMS) for the glass substrate (Fig. 6a) is 1.8 ± 0.1 nm and 11.5 ± 4.0 nm for the PET substrate (Fig. 6b). The RMS values of the DMD electrodes are even reduced, yielding RMS = 1.0 ± 0.1 nm for glass/MTO40/Ag14/MTO10/30 (Fig. 6c) and RMS = 4.8 ± 2.0 nm for PET/MTO40/Ag14/MTO10/30 (Fig. 6d). NANOSENSORS silicon high-resolution AFM probes for tapping mode with a typical AFM tip radius of 2 nm ( SuperSharpSilicon™ SSS-NCHR ) were used.

The application of molybdenum oxide layers in electronic devices like solar cells and organic light emitting diodes (LEDs) has expanded considerably. * Dielectric/metal/dielectric (DMD) transparent… Read More »Transparent electrodes based on molybdenum-titanium-oxide with increased water stability for use as hole-transport/hole-injection components
