Lecture

Tunneling Current: Fundamentals

Description

This lecture covers the fundamentals of tunneling current, including the elementary qualitative model and spectroscopy of density of states. It explains the transmission of wavefunctions through barriers, the dependence of transmission probability on energy and barrier properties, and the manipulation and imaging of single atoms using scanning tunneling microscopy. The lecture also discusses conductance quantization, as observed in gold wires, and provides experimental evidence supporting this phenomenon.
