The photoconductivity of a nanocomposite MEH-PPV:TiO2 thin film is investigated. The nanocomposite MEH-PPV:TiO2 thin film was deposited on a glass substrate by spin coating technique. The composition of the TiO2 powder was varied from 5 wt% to 20 wt% (with 5 wt% interval). The concentration of the MEH-PPV is given by 1 mg/1 ml. The current voltage characteristics were measured in dark and under illumination. The photoconductivity showed increment in value as the composition of the TiO2 is raised in the polymer based solution. The absorption showed augmentation as the amount of TiO2 is increased. The escalation of the current voltage is then supported by the results of surface morphology.

Работа посвящена разработке модульной четрырехзондовой установки с использованием жидкого контакта на основе индий-галлиевого эвтектического раствора (EGaIn), с помощью которого можно создать прижимные жидкие контакты, не вносящие механические деформации в измеряемые структуры. Предлагается использовать данную установку для измерения вольт-амперных характеристик тонкопленочных образцов. Предполагается модульная схема измерений. Каждый зонд управляется четырьмя моторами для позиционирования и выдавливания капли из шприца для формирования нужного размера пятна контакта. Используется оптический контроль для подготовки зондов и измерения диаметра сформированных контактных областей. Подобраны параметры изготовления жидких зондов, а именно скорости выдавливания и перемещения зонда вдоль вертикальной оси для формирования капли конической формы . Управление установкой осуществляется в среде LabView. The work is devoted to development of a modular four-probe setup using a liquid contact based on an indium-gallium eutectic solution (EGaIn), which can be used to create clamping liquid contacts that do not introduce mechanical deformation into the measured structures. It is proposed to use this setup for measuring the current-voltage characteristics of thin-film samples. A modular measurement scheme is assumed. Each probe is driven by four motors to position and expel a drop from the syringe to form the desired contact area size. Optical control is used to prepare the probes and measure the diameter of the formed contact areas. The parameters for the manufacture of liquid probes are selected, namely, the speed of extrusion and movement of the probe along the vertical axis to form a conical droplet. The installation is controlled in the LabView environment.
