Dear Alex and kind users,
In the experiment, if I get a single crystal material, for example, I have MoS2. The whole sample is 14 micrometer, is there any possible having a grain boundary scattering in it? Without boundary scattering, I obtained the mobility is around 10^4 cm^2/Vs at 10 K. But the measured data is around 100. I am very confused that what is the reason for this big gap between theory and experiment. I set: scattering_type: [IMP, ADP, POP, PIE]. However, when I added the boundary scattering in the amset, the data is reduced to around 500. I am wondering that what is the condition for adding the boundary scattering? My friends told me that a single crystal has no boundary scattering which only occurs at polycrystalline. Could you give me some suggestions?
