Dr Prashant Ghediya is a Postdoctoral Research Fellow at Hokkaido University. He is a former recipient of the Chennupati and Vidya Jagadish Visiting Scholarship and Fellowship Awards. His current research activities include:
1. Fabrication of transperent oxide semiconductor thin film transistors (TFTs)
2. Direct ink coating of new emerging materials for solar PV
My current research is focused on high mobility oxide semiconductor (IGZO, In2O3) thin film transistors (TFTs). We fabricate high mobility oxide semiconductor thin films, as an active channel layer, from ceramic target by pulsed laser deposition (PLD) technique at room temperature with different oxygen pressure and annealing temperatures. The physical properties of the oxide semiconductor thin films have been analyzed by a range of techniques including X-ray diffraction, UV−vis−near-infrared (NIR) spectrophotometer, thermopower measurement, dc four probe measurement, low-temperature probing station using TMP, etc. We clarify the operational mechanism of oxide TFTs by electric field thermopower modulation technique.
Alternatively, my current research interests include direct ink coating (Ultrasonic spray coating, inkjet printing, doctor blading, dip coating, etc.) of new emerging materials for solar cells.
If you are interested in my research activities, please do not hesitate to contact me.
