Magnetoconductivity behaviour due to electron–electron interactions, weak localization and Zeeman effects in 2-D-layered WS2

Here, we studied the behaviour of magnetoconductivity (MC) as a function of temperature and magnetic field on sample of 2-D-layered WS2. In fact, in our model, we re-analysed experimental measurements obtained by Zhang et al ( J. Appl. Phys. Lett. 108:153114, 2016). The experimental values of MC wil...

Description
Summary:Here, we studied the behaviour of magnetoconductivity (MC) as a function of temperature and magnetic field on sample of 2-D-layered WS2. In fact, in our model, we re-analysed experimental measurements obtained by Zhang et al ( J. Appl. Phys. Lett. 108:153114, 2016). The experimental values of MC will be confronted with complex theoretical models to provide physical explanations for the change of sign of the MC when the temperature decreases and magnetic field increases. We developed a theoretical model indicating the contributions to the MC due to electron–electron interaction effects, weak localization effect and Zeeman effect. Several scale parameters were compared with each other to highlight their respective influence on the behaviour of MC, such as the coherence length L φ , interaction length L int and magnetic length L B .
