Introducing Measurement Hardware

This lecture covers the introduction of measurement hardware, reviewing the Hertz calculation, and demonstrating low resistance measurement using analog electronics. The instructor explains how to measure the real area of contact in a junction and the importance of Young's Modulus and Poisson Ratio in determining junction resistivity. Students will learn about the physical experiment layout, the delta mode method for low noise measurements, and how to connect remotely for measurements. The lecture concludes with a demonstration of low-R measurements using specialized equipment.
