Polarization engineered all 2D Graphene/Ferroelectric hybrid for persistence-free photoresponse
Navkiranjot Kaur Gill, Shaili Sett, Saloni Kakkar +3
Graphene-based van der Waals hybrid photodetectors typically work on trap-mediated photogating mechanism, exhibiting high sensitivity, but under-perform in the fast detection of re…
Moire-Engineered Ferroelectric Transistors for Nearly Trap-free, Low-Power and Non-Volatile 2D Electronics
Arup Singha, Shaili Sett, Kenji Watanabe +3
Long-range moire patterns in twisted WSe2 enable a built-in, moire-length-scale ferroelectric polarization that can be directly harnessed in electronic devices. Such a built-in fer…
Emergent inhomogeneity and non-locality in a graphene field-effect transistor on a near-parallel moire superlattice of transition metal dichalcogenides
Shaili Sett, Rahul Debnath, Arup Singha +9
At near-parallel orientation, twisted bilayer of transition metal dichalcogenides exhibit inter-layer charge transfer-driven out-of-plane ferroelectricity that may lead to unique e…
Tuning exciton complexes in twisted bilayer WSe2 at intermediate misorientation
Rahul Debnath, Shaili Sett, Sudipta Kundu +5
Twist angle modifies the band alignment, screening, and interlayer (IL) coupling in twisted bilayers (tBLs) of transition metal dichalcogenides. Intermediate misorientation (twist…
Effective separation of photogenerated electron-hole pairs by radial field facilitates ultrahigh photoresponse in single semiconductor nanowire photodetectors
Shaili Sett, Arup Kumar Raychaudhuri
We report an investigation on the observation of ultrahigh photoresponse (photogain, G_Pc>106) in single nanowire photodetectors of diameter < 100 nm. The investigation which is a…
Broad Band Single Germanium Nanowire Photodetectors with Surface Oxide Controlled High Optical Gain

We have investigated photoconductive properties of single Germanium Nanowires(NWs)of diameter less than 100 nm in the spectral range of 300 to 1100 nm showing ultra large peak Resp…
Enhanced broad band photoresponse of a partially suspended horizontal array of Silicon microlines fabricated on Silicon-On-Insulator wafers
Shaili Sett, Vishal Kumar Aggarwal, Achintya Singha +2
We report a high Responsivity broad band photo-detector working in the wavelength range 400 nm to 1100 nm in a horizontal array of Si microlines (line width ~1 micron) fabricated o…
Temperature-dependent thermal conductivity of a single Germanium nanowire measured by Optothermal Raman Spectroscopy
S. Sett, V. K. Aggarwal, A. Singha +1
We investigate temperature dependent thermal conductivity k(T) in a single Ge nanowire (NW) using Optothermal Raman Spectroscopy which utilizes the temperature dependence of Raman…
