Here we present compelling evidences that CH3NH3PbI3 crystals self-grown on FTO/TiO2 substrate consist of ferroic domains with alternating polar and nonpolar orders, in contrast to previous experimental and theoretical expectations, and polar domains possess reduced photocurrent. It is found that polar...

Nevertheless, the exact atomic structure of OIHPs is still unsettled, with two possible space groups, polar I4cm and nonpolar I4/mcm still hotly debated depending on the orienta- tions of polar ions such as MA+ 14. While many perovskite oxides are polar with strong ferroelectricity, the ...
Are hydrogen bonds polar or nonpolar? Why is water a polar compound? What type of bond forms between water molecules? What's the difference between a dipole and a polar molecule? Which one of the following gases would deviate the least from ideal gas beha...
Using a relatively simple arrangement of parallel columns, one can potentially effect the separation of a wide variety of both polar and nonpolar compounds and monitor the elution times with only one GC detector. Specifically, O22, N22, N22O, and NH33 have been separated using one detector....
