Performance Analysis of Organic LED and Transistor Based Sensor for Bio Medical Application

Abstract

Organic electronics is an emerging technological domain pertaining to the development and realization of flexible devices. Organic semiconductor materials (Polymers and small molecules) have captivated attention of the research community by the virtue of actualizing large area electronic circuits over unconventional substrate such as; plastic, paper, fibre etc. Further, fabrication of economically feasible devices is attributed to the low temperature solution processes including dip coating, screen printing, spin coating and inkjet printing. Organic devices possess an interdisciplinary facet that can be utilized in the different field; communication, memory devices, bio-degradable technology, sensor application etc. owing to their robustness, light weight and low power requirements. Commercial success is achieved in the form of utilizing the organic light emitting diodes (OLEDs) based practical displays by acclaimed technological giants. newlineRecently, international technology roadmap for semiconductors (ITRS) has affirmed the organic electronics to be one of the most promising research areas. The proposed work is focused on the development of a sensor application based on the organic LEDs for the diagnosis of Ovarian Cancer . The work is carried out in four different phases wherein, each phase focuses on a particular aspect that is important for the development of organic sensor. The OLED utilized in the sensor should exhibit impeccable performance. Therefore, the primary focus is to develop an OLED with good luminescence characteristics to enable a precise light detection capability. Consequently, first two phases of the work are focused on the architectural aspect for the OLED device. Thereafter, mathematical modeling and internal device analysis is performed in the phase three with a view-point of an in-depth understanding of the performance parameters. Finally, a comprehensive analysis is carried out to utilize the OLED in the sensor application. newlineDifferent layers incorporated in the multi-layered OLED architect
