Conductance quantum - Wikipedia
The conductance quantum, denoted by the symbol G0, is the quantized unit of electrical conductance. It is defined by the elementary charge e and Planck constant h as: $${\displaystyle G_{0}={\frac {2e^{2}}{h}}=4\alpha \epsilon _{0}c}$$ = 7.748091729...×10 S. It appears when measuring the … 展开
Quantized conductance occurs in wires that are ballistic conductors, when the elastic mean free path is much larger than the length of the wire: $${\displaystyle l_{\rm {el}}\gg L}$$ . … 展开
