Article Abstract Index3

This study explains STM theory and tunneling principles while evaluating an STS-based research paper, emphasizing its methods, findings, and significance in understanding surface structure and electronic properties at the nanoscale. Human is curious by nature and that leads him to explore the enormous mysteries of the universe. The journey of knowledge has started from the very early days of the human civilization. Scientists have invented various tools to study their desirables outstretched between the cosmos and the subatomic realm. One of the edge cutting invention is the Scanning Tunneling Microscope (STM) which is developed by Gerd Binnig and Heinrich Rohrer in the early period of 1980s in the IBM research laboratory, Zürich. This revolutionary invention has provided the insight to the subatomic world which is beyond our optical vision. This miracle instrument can provide a real space image at subatomic level and also can manipulate individual atoms and molecules. Very local detailing of molecules such as surface defects, electrical properties, band structure and many more properties can be obtained using this device. In the year of 1986 Gerd Binnig and Heinrich Rohrer have been honored with the most prestigious the Noble prize for this groundbreaking invention.
