Reverse Monte Carlo applications in disordered systems

Crystallography can only provide information about the averageatomicstructureof a crystal.However, the full scatteringmethodcombinedwith the ReverseMonteCarlo(RMC)simulationhas a uniqueadvantageof providingmultipleinformationregardinga crystal,includingthe averageatomicstructure,atomicspacing,bondangles,orientation,anddeformationof the structuralpolyhedronat the localscale.Recently, with the help of the third-generationsynchrotronand spallationneutronsources,the RMCmethodhas undergonerapidexperimentaland theoreticaldevelopment.Additionally, owingto its high-qualitydata,the RMCmethodis widelyused to studythe localfluctuationsand finestructureof disorderedmaterials.This paperintroducesthe RMCmethodin a disorderedsystemby describingits basicprinciplesand analysismethodsand illustratesa seriesof RMCmodelcasesbeneficialfor us to understandthe RMCmethod.Finally, the futuredevelopmentof the RMCmethodis discussed.Recently, China's investmentin researchequipmentfor universitieshas grownexponentially, and we believethat the RMCmethodwith the fourthgenerationofhigh-energylight sourceswill play an importantrole in the design and development of various novel materials
