Organic Electronics & Materials Research Laboratory
Department of Physics & Astrophysics, University of Delhi, India
ORGANIC ELECTRONICS AND MATERIALS RESEARCH LABORATORY was established in 2009 with the aim to study fundamental electronic charge transport properties of the polymers, graphene derivatives and small molecules for device applications. We carry out the synthesis of bulk polymers as well as their nanostructures like nanotubes, nanowires, nanoparticles or nanospheres, nanosheets, etc. These conducting polymers are polythiophene, polypyrrole, polyaniline, their copolymers and their nanocomposites with other materials such as metal oxides, graphene and graphene derivatives like reduced graphene oxide. The synthesized materials are explored for various applications like solar cells, Schottky junctions, OLEDs, EMI shielding, gas sensing, electrochromic devices, supercapacitors etc.
Initiated as DST project SR/S2/CMP-0099/2010, the research work on the development of gas sensors has been going on in our lab for more than 10 years now. We have assembled indigenous setups for sensing toxic gases and volatile vapors. The setups are fully automated using LabView and FlowVision software. Another important project completed recently is on the fabrication and study of electrochromic devices for smart window applications. Further research work is still being pursued in our lab in the same field. We are also on our way towards the development of small molecules for OLED applications. For the fundamental study of charge transport properties, we have our own designed setups to carry out dc and ac conductivity measurements. All the related equipment like Keithley’s 236 source-meter unit, Keithley’s 2000 DMM, Keithley’s 6487 picoammeter, Wayne Kerr’s 6540 Network Analyser, Autolab PGSTAT204, etc. are available in our lab. The research scholars in our lab get holistic experimental training from synthesis of materials to designing and assembly of equipment alongwith their operation and maintenance.
