An alternative method of image simulation in high resolution transmission electron microscopy
Usha Bhat, Ranjan Datta
An alternative approach to the image simulation in high resolution transmission electron microscopy (HRTEM) is introduced after comparative analysis of the existing image simulatio…
Insights and alternative proposals on the phase retrieval in high resolution transmission electron microscopy
Usha Bhat, Ranjan Datta
Alternative reconstruction method is proposed on retrieving the object exit wave function (OEW) directly from the recorded image intensity pattern in high resolution transmission e…
Heterostructures of hetero-stack of 2D TMDs (MoS2, WS2 and ReS2) and BN
Badri Vishal, Usha Bhat, H. Sharona +1
In this manuscript, we describe optical emission of heterostructure of hetero-stack between 2D TMDs (MoS2, WS2, and ReS2) and BN. Similar to our previous results on the stack of si…
Growth of epitaxial ReS2 thin film by pulsed laser deposition
B. Vishal, H. Sharona, U. Bhat +7
We present results on growth of large area epitaxial ReS2 thin film both on c plane sapphire substrate and MoS2 template by pulsed laser deposition (PLD). Films tend to grow with (…
Quantitative atom counting of Zn and O atoms by atomic resolution off-axis and in-line holography
Usha Bhat, Ranjan Datta
Quantitative atom counting of Zn and O atoms in zinc oxide(ZnO)epitaxial thin film by three different routes; reconstruction of phase from side and central band of atomic resolutio…
Chemically stabilized epitaxial wurtzite-BN thin film
Badri Vishal, Rajendra Singh, Abhishek Chaturvedi +6
We report on the chemically stabilized epitaxial w-BN thin film grown on c-plane sapphire by pulsed laser deposition under slow kinetic condition. Traces of no other allotropes suc…
Distinct photoluminescence in multilayered van der Waals heterostructures of MoS2/WS2/ReS2 and BN
U. Bhat, R. Singh, B. Vishal +4
Van der Waals heterostructures of (TMDL=1/BNL=1-4/TMDL=1/BNL=1-4), [TMD = MoS2, WS2, and ReS2] are grown on c-plane sapphire substrate by pulsed laser deposition under slow kinetic…
Surface spin canting in Fe3O4 and CoFe2O4 nanoparticles probed by high resolution electron energy loss spectroscopy
