Polarization switching in PVDF ferroelectric polymer composites containing grap...
Bystrov, Vladimir; Paramonova, Ekaterina; Bystrova, Anna; Shen, Hong; Meng, XiangjianIn this work molecular modeling and quantum molecular dynamic (MD) calculations studies composite nanostructure containing ferroelectric polymer PVDF and graphene layers were carried out using HyperChem software and PM3 semi-empirical method. It is shown that the inclusion (addition) of graphene layers to the ferroelectric PVDF polymer increases the coercive field of the composite structure and decreases the po...

Bystrov, V. S.; Paramonova, E. V.; Sapronova, A. V.; Shen, Hong; Meng, Xiangjian; Wang, Jianlu; Avakyan, L. A.Transition metal dichalcogenide MoS2 monolayers is very promising for many applications, especially in the fields of optics as emitters and detectors, in electronics as transistors. It is first of all due that they have a direct band gap Eg, which is dependent on external applied electric fields. To create such an electric field, it is proposed to use the field induced polarization of ferroelectric polymers suc...
