In the SI unit of mobility, V stands for voltage or electric potential difference. The mobility of a charge carrier, such as an electron or hole, is defined as the ratio of the drift velocity (V_d) to the applied electric field (E).
The formula for mobility \( \mu \) is:
\[
\mu = \frac{V_d}{E}
\]
Where:
So, in this context, V refers to the voltage or potential difference that causes the electric field, which is related to the mobility of charge carriers. The units of mobility are typically given as m²/(V·s).
The formula for mobility \( \mu \) is:
\[
\mu = \frac{V_d}{E}
\]
Where:
- \( \mu \) is the mobility (in units of m²/V·s).
- \( V_d \) is the drift velocity (in meters per second, m/s).
- \( E \) is the electric field (in volts per meter, V/m).
So, in this context, V refers to the voltage or potential difference that causes the electric field, which is related to the mobility of charge carriers. The units of mobility are typically given as m²/(V·s).
