Abstract

We have studied the transport properties in metallic n-type InP semiconductor. We show that the dependence on temperature of metallic electrical conductivity obey to the law 𝜎 = 𝜎(𝑇 = 0) + 𝑚𝑇1/2. We highlight the absence of a minimum electrical conductivity 𝜎𝑚𝑖𝑛 proposed by Mott at the metal-insulator transition. We show that the conductivity at temperature T = 0 K, 𝜎(𝑇 = 0) , follows a scaling law as a function of the effective parallel and perpendicular Bohr radii 𝑎∥ and 𝑎⊥.

金属n型InP中连续金属-绝缘子过渡和结垢规律

研究了金属n型InP半导体的输运性质。表明金属电导率对温度的依赖性服从规律:φ = φ(𝑇= 0)+𝑚𝑇1/2。我们强调了Mott在金属-绝缘体过渡中提出的最小电导率的缺失。我们表明，温度T = 0 K时的电导率，φ(𝑇= 0)遵循一个标度定律，作为有效平行和垂直玻尔半径𝑎∥和𝑎⊥的函数。
