'''TMDCA''' has notably elucidated [[Anderson localization]], offering a mean-field model that precisely captures the re-entrance of the mobility edge in the three-dimensional [[Anderson model]].<ref name=":2" /> TMDCA clearly delineates the metal-insulator transition in weakly interacting disordered electron systems, highlighting that interactions stabilize the metallic phase and induce a soft pseudogap near the critical disorder strength.<ref name=":4" /> Furthermore, it confirms that the mobility edge remains stable as long as the chemical potential exceeds or meets the mobility edge energy. TMDCA also sheds light on the cause of photoluminescent quenching in two-dimensional <math>MoS_2</math> observed experimentally and defect-tolerant behavior in 2D monolayers PbSe and PbTe where impurity states forming shallow levels rather than localized deep levels. <ref name=":5">{{cite journal | last1=Ekuma | first1=C.

Sir I would like to know more about TMDCA, it's an interesting area of research
