Interplay of spin-lattice and electronic coupling far above Neel ordering in 2D antiferromagnetic CrPS4 and its interface manifestation

Divya Jangra, Binoy Krishna De, Mukesh Kumar Dasoundhi, Sourav Chowdhury et autres

A short-range spin correlation driven, strongly intercoupled spin-phonon-electronic state far above TN (~38K) is identified in the low dimensional van der Waals antiferromagnet CrPS4. Temperature-dependent Raman spectroscopy reveals spin-phonon coupling persisting up to T*~120K, concomitant with local lattice distortion. The setting of …

Metal‐Ligand Coordination Enables Molecular Resist‐Based Direct Write Lithography of Metal Halides

Prakash Sarkar, Gurupada Ghorai, Harihar Mondal, Shivani Malvi et autres

ABSTRACT Lithographic patterning of semiconductor materials is essential for most modern optoelectronic devices. However, traditional inorganic and nanocrystal derived resists exhibit low electron‐dose sensitivity, weak solubility contrast, and limited chemical compatibility, restricting high resolution functional lithography. Here, we present a molecular complex …

Correlated transport and spectroscopic investigations of defect-mediated electronic conduction in Bi 2 SeTe 2

Shiwangi Puri, S. Giri, M. Manna, Binoy Krishna De et autres

This study investigates the electronic and lattice properties of single-crystalline Bi2SeTe2(BST) to deepen the understanding of its topological behavior and defect-mediated transport mechanisms. Here, we combine results from low-temperature scanning tunneling microscopy and spectroscopy (STM/STS), temperature-dependent transport measurements, and Raman spectroscopy to …

Enhanced electron–phonon coupling due to layered-perovskites octahedral tilting in hole doped cuprate superconductor

Isha Isha, Deobrat Singh, Hemant Singh Kunwar, Suman Karmakar et autres

The electron-phonon (e-ph) coupling is crucial in explaining various ordering phenomena such as superconductivity and charge density waves (CDW) which has been invoked to explain Cooper pair formation leading to superconductivity, however, the origin of charge state mechanism is not yet fully …

Stranski–Krastanov growth of disordered ScNx thin films on MgO(100): Influence of defect densities on electronic structure and transport properties

Susmita Chowdhury, Rachana Gupta, Najnin Bano, Yogesh Kumar et autres

We report a real-time Stranski–Krastanov growth of reactively sputtered ScNx thin films on MgO(100). The epitaxial growth was limited to 5 nm at a substrate temperature (Ts) of ∼25 °C, while the self-sustaining epitaxial nature along the [100] azimuth was retained up …
