Micro and Nano Devices Laboratory

The laboratory has been planned by keeping both the teaching and research requirements of SENSE. With the existing of Curriculum for Applied Learning (CAL) theme, the Micro and Nano Devices Laboratory caters to courses in the UG as well as PG curriculum including Final Year Project. UG and PG students are doing their RBL and Final year projects in different domains of expertise of the faculty of the Micro and Nano Devices Group.
The laboratory has been planned for MEMS design (using commercially available CAD tools such as Intellisuite), Nanoelectronic Device Simulations using TCAD Sentaurus tools and Synthesis and Characterization of Novel Nanomaterials towards Micro and Nano Devices fabrication activities.
