Circular ferroelectric tunnel junctions for the improvement of memory window and endurance

نویسندگان

چکیده

Abstract A circular ferroelectric tunnel junction (C-FTJ) is proposed for larger memory window and better endurance than a conventional planar FTJ (P-FTJ). The electrical characteristics of the C-FTJ are evaluated compared with P-FTJ by using device simulation. It confirmed that C-FTJs have more excellent switching P-FTJs because electric field becomes concentrated across layer. Also, show applied to interfacial layer alleviated.
