The Hall coefficient is theoretically studied in a rectangular quantum wires with infinitely high potential subjected to a crossed dc electric field and magnetic field in the presence of a high frequency electromagnetic wave (EMW). By using the quantum kinetic equation for electrons interacting with optical phonons, analytical expressions for the conductivity tensor as well as the Hall coefficient in a rectangular quantum wires is obtained. The results are numerically evaluated and graphed for GaAs/GaAsAl rectangular quantum wire to show clearly the dependence of Hall coefficient (HC) on a length rectangular quantum wires with different temperature values. We can see the length of the small increase in the value domain Hall coefficient increased, further increasing the length of the Hall coefficient continues to increase and reaches a constant value.
