Metal oxide-Nanostructure Thin Film Lab
In a day, when you don't come across any problems-you can be sure that you are travelling in a wrong path

Welcome To MONTFL
Our team focuses on different solution processed thin film deposition for various applications like electronics/optoelectronics, energy and health. We primarily concentrate on sol-gel derived ion-conducting metal oxide, metal oxide semiconductors and various nanostructured materials for thin film deposition. Ion-conducting oxide thin film has mobile light atoms like Li+, Na+, K+ which can move easily through the solid thin film. This kind of ionic thin film has very high areal capacitance which can be suitable for fabricating low operating voltage thin film transistors (TFTs). Besides, light atoms of ionic oxide can be exchanged easily with other ions like Ag+, Au+, Cu+, which allow us to grow different metal and metal chalcogenide nanocrystal inside oxide materials. These metal /metal oxide or metal chalcogenide /metal oxide thin film has various applications for optoelectronics devices and energy generation. Besides, we grow different nanocrystal by microwave assisted synthesis, hot-injection and hydrothermal process for thin film device application.
ION CONDUCTING OXIDE DIELECTRIC FOR TFT APPLICATIONS
The basic objective of our present work is to fabricate the cost-effective ion conducting dielectric based high-performance, low operating voltage thin film transistor (TFT). Their coherent interface formation with solution-processed oxide semiconductors lead to considerable improvements in TFT performance and make it possible to all solution processed and printable TFT fabrication.
ENERGY HARVESTING DEVICES
Our group is developing the piezo-potential self-biased thin film transistor technology for mechanical energy harvesting applications. The major goal of this endeavor is to create a portable gadget that can sense and store mechanical energy produced by human body activity or different natural vibration.
PHOTODETECTORS
Our group is synthesizing the QDs by microwave & hot injection synthesis and by using those QDs we are fabricating photoconductors and photodiodes.
mEMORY AND SYNAPTIC DEVICES
Our work focus on inorganic ,solution process, low cost fabrication of memory devices and towards its implementation into synaptic applications. Besides we are also working on interface based organic memory devices.
TRANSPARENT CONDUCTORS
Our primary objective is to create transparent conducting thin films made of inorganic low cost solution process for use in a variety of applications.
Light Emitting Transistors
Our work is to fabricate a LET by using emissive layer with the help of electron transport layer and Hole transport layer.
