Item Energetics and Electronic Properties of Pt Wires of Different Topologies on Monolayer MoSe 2(AIP Publishing, 2016) Jamdagni, Pooja; Kumar, Ashok; Thakur, Anil; Pandey, Ravindra; Ahluwalia, P. K.The energetics and electronic properties of different of Pt wires including linear, zigzag and ladder structures on MoSe2 have been investigated in the framework of The predicted order of stability of Pt wire on MoSe2 is found to be: linear > ladder > zigzag. Pt wires induce states near the of MoSe2 that results into metallic characteristics of Pt-wire/MoSe2 assembled system. signifies most of the contribution from Pt atoms near the Fermi energy of assembled wire/MoSe2 system. These findings are expected to be important for the of based on MoSe2 layers for flexible nanoelectronics.Item Interactions of Gas Molecules with Monolayer MoSe 2 : A First Principle Study(AIP Publishing, 2016) Sharma, Munish; Jamdagni, Pooja; Kumar, Ashok; Ahluwalia, P. K.We present a first principle study of interaction of toxic gas molecules (NO, NO2 and SO2) with MoSe2. The predicted order of sensitivity of gas molecule is NO2 > SO2 > NO. strongly influence the electronic behaviour of MoSe2 by inducing in the vicinity of Fermi energy. NO and SO2 is found to induce p-type effect while to metallic transitions occur on NO2 Our findings may guide the experimentalist for sensor based on MoSe2
