Intrinsic Ferroelectric Properties of Strained Tetragonal PbZr0.2Ti0.8O3 Obtained on Layer–by–Layer Grown, Defect–Free Single–Crystalline Films

Probing intrinsic polarization properties in bismuth-layered ferroelectric films

Columnar grown copper films on polyimides strained beyond 100%

Many flexible electronic devices contain metal films on polymer substrates to satisfy requirements for both electrical conductivity and mechanical durability. Despite numerous trials to date, the stretchability of metal interconnects remains an issue. In this paper, we have demonstrated a stretchable metal interconnect through control of the texture of a copper film with columnar grown grains o...

Ferroelectric properties of Bi3.25La0.75Ti3O12 thin films grown on the highly oriented LaNiO3 buffered PtÕTiÕSiO2 ÕSi substrates

Bi3.25La0.75Ti3O12 ~BLT! thin films were grown on Pt/Ti/SiO2 /Si and on LaNiO3 ~LNO! buffered Pt/Ti/SiO2 /Si substrates using sol-gel processing. Scanning electron micrographs showed the BLT films are composed of peg-like or platelet-like grains depending upon annealing temperature and the substrate type. Large platelet grains were found in BLT films deposited on the LNO/Pt/Ti/SiO2 /Si substrat...

Tetragonal CH3NH3PbI3 is ferroelectric.

Halide perovskite (HaP) semiconductors are revolutionizing photovoltaic (PV) solar energy conversion by showing remarkable performance of solar cells made with HaPs, especially tetragonal methylammonium lead triiodide (MAPbI3). In particular, the low voltage loss of these cells implies a remarkably low recombination rate of photogenerated carriers. It was suggested that low recombination can be...

Scanning X-ray nanodiffraction from ferroelectric domains in strained K0.75Na0.25NbO3 epitaxial films grown on (110) TbScO3 1

Scanning X-ray nanodiffraction on a highly periodic ferroelectric domain pattern of a strained K0.75Na0.25NbO3 epitaxial layer has been performed by using a focused X-ray beam of about 100 nm probe size. A 90°-rotated domain variant which is aligned along [1[Formula: see text]2]TSO has been found in addition to the predominant domain variant where the domains are aligned along the [[Formula: se...
