Growth and atomically resolved polarization mapping of ferroelectric thin film
Jihwan Jeong, Junsik Mun, Saikat Das +5
Aurivillius ferroelectric (BWO) encompasses a broad range of functionalities, including robust fatigue-free ferroelectricity, high photocatalytic activity, and ionic con…
Deterministic influence of substrate-induced oxygen vacancy diffusion on thin film growth
Saikat Das, Tadakatsu Ohkubo, Shinya Kasai +1
In oxide epitaxy, the growth temperature and background oxygen partial pressure are considered as the most critical factors that control the phase stability of an oxide thin film.…
Enhanced flexoelectricity at reduced dimensions revealed by mechanically tunable quantum tunnelling
Saikat Das, Bo Wang, Tula R. Paudel +5
Flexoelectricity is a universal electromechanical coupling effect whereby all dielectric materials polarize in response to strain gradients. In particular, nanoscale flexoelectrici…
Electronic Reconstruction Enhanced Tunneling Conductance at Terrace Edges of Ultrathin Oxide Films
Lingfei Wang, Rokyeon Kim, Yoonkoo Kim +10
Quantum mechanical tunneling of electrons across ultrathin insulating oxide barriers has been studied extensively for decades due to its great potential in electronic device applic…
Overcoming the Fundamental Barrier Thickness Limits of Ferroelectric Tunnel Junctions through BaTiO3/SrTiO3 Composite Barriers
Lingfei Wang, Myung Rae Cho, Yeong Jae Shin +5
Ferroelectric tunnel junctions (FTJs) have attracted increasing research interest as a promising candidate for non-volatile memories. Recently, significant enhancements of tunnelin…
