Resumen

An automated installation based on National Instruments equipment, two installations for applying organic coatings are implemented. The installation of a thermo vacuum evaporation with a virtual device "ThermoVac" allows linear heating of the evaporated substance at a fixed rate of up to 500 ° C. The centrifugal centrifugation unit with an VI “SC_organic” supports the specified rotation speed of the substrate in the range of 500 to 9000 rpm. Based on the microprobe station Cascade Microtech MPS150, an automated channel was developed for testing memristor structures, in the mode of multiple reading and writing. VI "RW MIM" forms a sequence of pulses of the specified amplitude and duration in the write / read modes at the SMU output of the source. The deposition and validation of 5,11-dimethyl-5,11-dihydroindolo [3.2-b] carbazole and 5,11-dihexyl-5,11-dihydroindolo [3.2-b] carbazole films was performed. From the measured volt-ampere characteristics, it was found that the semiconductor in the synthesized TiN / DMICZ / Au, Ti / DMICZ / Au structures has a hole conductivity with a mobility μ = 4.9 ∙ 10-7 cm2/(V∙s). It is shown that the recorded I-V characteristic is characterized by hysteresis loops that indicate the presence of a memorial effect in TiN / DHICZ / Au samples. The testing of layered structures under test in multiple read / write modes was performed.
