Description
The average charge number on the metallic single electron transistor due to the effect of Coulomb Blockade and Electron Tunneling at any temperature is calculated by using path integral Monte Carlo (PIMC) approaches. The results show that those effects are the most prominent at low temperatures, i.e. $\beta {E_C} > 1$. Additionally, the efficiencies of the Single Site Update Algorithm (SSU) and Fast Fourier Transform Algorithm (FFT) techniques are compared. We found that the FFT technique needed significantly less processing time that SSU method. In essence, the processing time of the FFT technique was approximately $38\%$ of that of the SSU method.
