Journal ArticleDOI
Schottky barrier heights for Au and Pd contacts to MoS2
Naveen Kaushik,Ankur Nipane,Firdous Basheer,Sudipta Dubey,Sameer Grover,Mandar M. Deshmukh,Saurabh Lodha +6 more
TL;DR: In this paper, the Schottky barrier heights for Au and Pd contacts to MoS2 were obtained by analysing low temperature transistor characteristics and contact resistance data obtained using the transfer length method.
Journal ArticleDOI
Dipolar interactions between localized interlayer excitons in van der Waals heterostructures
TL;DR: Repulsive dipole–dipole interactions between localized interlayer excitons are shown to modify the optical response of van der Waals heterobilayers, forming the basis to obtain strong optical nonlinearity and excitonic many-body states in two-dimensional materials.
Journal ArticleDOI
A facile process for soak-and-peel delamination of CVD graphene from substrates using water.
Priti Gupta,Pratiksha D. Dongare,Sameer Grover,Sudipta Dubey,Hitesh Mamgain,Arnab Bhattacharya,Mandar M. Deshmukh +6 more
TL;DR: The process allows the reuse of substrates and hence can enable the use of oriented substrates for growth of higher quality graphene, and is an inherently inexpensive and scalable process for large-area production.
Journal ArticleDOI
Entanglement of single-photons and chiral phonons in atomically thin WSe 2
Xiaotong Chen,Xin Lu,Sudipta Dubey,Qiang Yao,Sheng Liu,Xingzhi Wang,Qihua Xiong,Lifa Zhang,Ajit Srivastava +8 more
TL;DR: In this article, the authors reported entanglement between collective, chiral vibrations in a two-dimensional WSe2 host and single-photons emitted from quantum dots (QDs) present in it.
Journal ArticleDOI
Tunable Superlattice in Graphene To Control the Number of Dirac Points
Sudipta Dubey,Vibhor Singh,Ajay K. Bhat,Pritesh Parikh,Sameer Grover,Rajdeep Sensarma,Vikram Tripathi,Krishnendu Sengupta,Mandar M. Deshmukh +8 more
TL;DR: In this article, a lateral superlattice was used to modify the band structure of graphene leading to the emergence of new Dirac cones, which persisted up to 100 K.
