Unit Information

Quantum_conductance

A fundamental constant in quantum electrical transport, specifically referring to the conductance quantum G₀ = 2e²/h, where e is the elementary charge and h is Planck's constant. This quantum of conductance represents the fundamental unit of electrical conduction through a single quantum channel and has the exact value of approximately 7.748091729 × 10⁻⁵ siemens. First observed in quantum point contacts and later in various mesoscopic systems, the conductance quantum plays a crucial role in the understanding of quantum transport phenomena. Essential for nanoscale electronics, molecular electronics, and the developing field of quantum information processing where discrete conductance values emerge from quantum mechanical principles.

Siemens

The SI derived unit of electrical conductance, named after German inventor and industrialist Ernst Werner von Siemens. Defined as the reciprocal of the ohm (1 S = 1 Ω⁻¹), representing the ability of a material to conduct electric current. One siemens is the conductance of a conductor in which one ampere of current flows when one volt of potential difference is applied across its terminals. Fundamental to characterizing conductive materials, electrolytes, and semiconductor devices. Essential in electrical engineering, materials science, and electrochemistry for quantifying how easily electric current can flow through substances and components.

Scientific Overview

Electric conductance is the measure of a material's ability to allow the flow of electric current. It is the reciprocal of resistance and is measured in siemens (S). Higher conductance indicates better conductivity.

Historical Background

The concept of conductance emerged as the inverse of resistance in electrical theory. Werner von Siemens contributed significantly to electrical engineering, and the unit siemens is named after him.
