Experimental Techniques in Nanotechnology
The aim of this course is to provide a general and broad introduction to the field of nanotechnology. During the course students will acquire the basic knowledge of the physical phenomena, theoretical concepts and experimental techniques behind the recent vastly improved ability to observe, fabricate and manipulate individual structures on the nanometer scale.
Course Outcome: On completion of the course, the student will be able to:
• Introduce the quantum mechanical aspects of nanotechnology
• Understanding nucleation, growth and phase transformation kinetics
• Comprehensive discussion on various methods of material Synthesis
• To Understand about different analysis techniques
