WebApr 15, 2010 · Hall Effect Measurements Introduction. The objective of this Web site is twofold: (1) to describe the Hall measurement technique for determining the carrier density and mobility in semiconductor materials and (2) to initiate an electronic interaction forum where workers interested in the Hall effect can exchange ideas and information. WebThis effect is known as Hall effect. What is the resistivity formula? Resistivity, commonly symbolized by the Greek letter rho, , is quantitatively equal to the resistance R of a specimen such as a wire, multiplied by its cross-sectional area A, and divided by its length l; = RA/l. The unit of resistance is the ohm.
