１．Synthesis and characterization of 2D materials.
２．Chemical modification of 2D materials.
３．Field Effect Transistor (FET) based biosensors.
１．Graphene: Single layer carbon (C) materials, where the C atoms are arranged in honeycomb lattice. It can be regarded as single layer of graphite. Graphene has the potential to revolutionize in the fields of electricity, conductivity, energy, batteries, sensors, medical diagnostic, coating and more.
２．Black Phosphorus: Black Phosphorus is a layered semiconducting material similar in appearance to graphite. Numerous applications in optoelectronic, semiconductor, and photovoltaic are expected. In a two-dimensional (2D) form, black phosphorus is known as Phosphorene.
３．Graphene Field Effect Transistor (GFET): The field-effect transistor (FET) is a type of transistor which uses an electric field to control the flow of current. FETs are devices with three terminals: source, gate, and drain. In GFET, graphene acts as conducting channel.
Two-dimensional (2D) materials are substances with a thickness of a few nanometres or less. Because of some extraordinary physical and chemical properties, 2D materials drawn much interest among the research community as the materials for next generation technology. To date, several hundred of different 2D materials including graphene, black phosphorous, silicone, germanene, h-BN, MXenes, etc. The 2D materials can show the properties of semiconductor, metal, semimetal, or superconductors. Along with the continued exploration of 2D materials, the need for synthesis/growth, characterization, and sensing application is highly desirable. Our laboratory focuses on the synthesis and characterization of graphene and black phosphorus followed by chemical functionalization. Using varieties of organic and inorganic approaches, these 2D materials are functionalized with varies of functional groups such as oxides, halide, hydrocarbons, thiol, metal nanoparticles, etc. For realization of practical application of 2D materials, we also work on fabrication and characterization of GFET focusing on biosensors and bioelectronics.
