Polar and apolar light-induced alignment of ferroelectric nematic at photosensitive polymer substrate
Ruslan Kravchuk, Oleksandr Kurochkin, Vassili G. Nazarenko +4
Surface alignment of a recently discovered ferroelectric nematic liquid crystal (NF) is usually achieved by buffed polymer films, which produce a unidirectional polar alignment of…
Helix alignment, chevrons, and edge dislocations in twist-bend ferroelectric nematics
Bijaya Basnet, Priyanka Kumari, Sathyanarayana Paladugu +6
We explore surface alignment and edge dislocations in the recently discovered twist-bend ferroelectric nematic, NTBF, in which the vector of spontaneous polarization follows an obl…
Director-layer dynamics in the antiferroelectric smectic-ZA phase of a ferroelectric nematic liquid crystal
Arjun Ghimire, Bijaya Basnet, Hao Wang +7
A dynamic light scattering study of director-layer fluctuations in the antiferroelectric smectic-ZA phase of the ferroelectric nematic liquid crystal DIO is reported. The dynamics…
Periodic splay Fréedericksz transitions in a ferroelectric nematic
Bijaya Basnet, Sathyanarayana Paladugu, Oleksandr Kurochkin +5
Electric field-induced splay of molecular orientation, called the Fréedericksz transition, is a fundamental electro-optic phenomenon in nonpolar nematic liquid crystals. In a ferro…
Confinement and magnetic field effect on chiral ferroelectric nematic in Grandjean-Cano wedge cells
Kamal Thapa, Olena S. Iadlovska, Bijaya Basnet +4
We explore the structure and magnetic field response of edge dislocations in Grandjean-Cano wedge cells filled with chiral mixtures of the ferroelectric nematic mesogen DIO. Upon c…
Chiral ground states of ferroelectric liquid crystals
Priyanka Kumari, Bijaya Basnet, Maxim O. Lavrentovich +1
Ferroelectric nematic liquid crystals are formed by achiral molecules with large dipole moments. Its three-dimensional orientational order is universally described as unidirectiona…
Ferroelectric nematic liquids with conics
Priyanka Kumari, Bijaya Basnet, Hao Wang +1
Spontaneous electric polarization of solid ferroelectrics follows aligning directions of crystallographic axes. Domains of differently oriented polarization are separated by domain…
Deposition of Reduced Graphene Oxide Thin Film by Spray Pyrolysis Method for Perovskite Solar Cell
Manoj Pandey, Dipendra Hamal, Deepak Subedi +4
The Perovskite absorber layer, the electron transport layer (ETL), the hole transport layer (HTL), and the transparent conducting oxide layer (TCO) are the major components that ma…
Synthesis and optical characterization of perovskite layer for solar cell application
Manoj Pandey, Dipendra Hamal, Bijaya Basnet +1
Solvent engineering offers fine control over the photovoltaic efficiency, film morphology, and crystallization quality of perovskite films and also enables to optimize light transm…
Soliton walls paired by polar surface interactions in a ferroelectric nematic liquid crystal
Bijaya Basnet, Mojtaba Rajabi, Hao Wang +5
Surface interactions are responsible for many properties of condensed matter, ranging from crystal faceting to the kinetics of phase transitions. Usually, these interactions are po…
