  This article reports the successful synthesis of single crystalline
two-dimensional thin flakes of NbSe$_2$. The XRD pattern of the grown crystal
ensured its crystallization in a single phase with a hexagonal structure. The
EDAX endorsed the stoichiometry of the as grown sample. To study the
vibrational modes, the Raman spectra were recorded, which exhibited the
expected four Raman active modes. The resistance vs temperature measurement
showed a well-established superconducting transition (Tc) at 7.3 K. The ZFC
(Zero-Field Cooled) & FC (Field Cooled) magnetization curves, as well as the
isothermal MH (Magnetization vs. field) measurements, have been performed for
both in plane and out-of-plane H directions. Distinct anisotropy is observed in
both magnetization and magneto-transport measurements with field direction,
leading to different critical fields (Hc). Out-of-plane magneto-transport data
hints towards the existence of a filamentary state. The density functional
theory (DFT) has been used to study the band structure of NbSe$_2$. Although
the bulk band structure confirmed metallic behavior, the same for mono-layers
of NbSe$_2$ within the GGA+U framework showed a band gap of 1.17eV. The article
addresses the anisotropy in the electronic and magneto-transport of 2D
superconductor NbSe$_2$.
