Characterization of ferroelectric domain walls by scanning electron microscopy
(Peer reviewed; Journal article, 2020)Ferroelectric domain walls are a completely new type of functional interface, which have the potential to revolutionize nanotechnology. In addition to the emergent phenomena at domain walls, they are spatially mobile and ... -
Determination of GaAs zinc blende/wurtzite band offsets utilizing GaAs nanowires with an axial GaAsSb insert
(Journal article; Peer reviewed, 2017)By applying a correlated micro-photoluminescence spectroscopy and transmission electron microscopy (TEM) approach, we have utilized molecular beam epitaxy grown self-catalysed GaAs nanowires (NWs) with an axial GaAsSb ... -
Electro-absorption of silicene and bilayer graphene quantum dots
(Journal article; Peer reviewed, 2016)We study numerically the optical properties of low-buckled silicene and AB-stacked bilayer graphene quantum dots subjected to an external electric field, which is normal to their surface. Within the tight-binding model, ... -
Epitaxial (100), (110), and (111) BaTiO3 films on SrTiO3 substrates — A transmission electron microscopy study
(Peer reviewed; Journal article, 2021)Chemical solution deposition (CSD) is a versatile method to fabricate oxide films. Here, the structure and local variations in the chemical composition of BaTiO3 (BTO) films prepared by CSD on (100), (110), and (111) SrTiO3 ... -
Interband transitions in narrow-gap carbon nanotubes and graphene nanoribbons
(Journal article; Peer reviewed, 2019)We use the robust nearest-neighbor tight-binding approximation to study the same footing interband dipole transitions in narrow-bandgap carbon nanotubes (CNTs) and graphene nanoribbons (GNRs). It is demonstrated that ... -
Multilayer phosphorene quantum dots in an electric field: Energy levels and optical absorption
(Journal article; Peer reviewed, 2018)Triangular and hexagonal multilayer phosphorene quantum dots with armchair and zigzag terminations are investigated with the orthogonal tight-binding model. The effect of increasing the number of layers is revealed. The ...
