[領域] 半導體物理 Experimental the resistivity is measured by preparing a rectangular sample Setting up a uniform current flow along the x-direction and measuring the longitudinal voltage drop Vx=(V1-V2) and transfer (or Hall) voltage drop VH=(V2-V3). Setting a constant current I, then the resistivity is readily to obtain as Rxx=Vx/I and Hall resistivity Rxy=VH/I. [題目] 1.Give an example where you can find R=0 for semiconductor. -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.112.231.218
