    • Band structure study of graphene and transition metal dichalcogenides heterostructures 

      Ahmed, Saif; Ahmed, Nafisa Nowshin; Nur, Juhayer An (BRAC University, 2017)
      According to Moore’s Law, it is predicted that the number of transistors –the building blocks of any modern electronic device– on integrated circuits per square inch will double every year. However studies show that the ...

    • Graphene based surface Plasmon polariton for plasmonic waveguide and devices 

      Nur, Salman Sadat; Zaman, Kashpia; Sarker, Md. Ashaduzzaman; Zarif, Abrar (Brac University, 2020-09)
      2D graphene was first discovered in 2004 and then it has gained admiration within scientific community due to its extraordinary electrical, mechanical, chemical and optical property. In this study, first we investigated ...

    • Humidity sensor using surface adsorbed channel modulated Graphene nanoribbon: NEGF approach 

      Shakil, Shifur Rahman; Zohra, Fatema Tuz; Pramanik, Parna; Tushar, Raihanul Islam (© 2014 Institute of Electrical and Electronics Engineers Inc., 2015-01)
      Electronic transport properties of Graphene nanoribbon (GNR) are explored by self-consistent numerical simulation. The effects of vapour (H2O) adsorption in GNR sheets on its current-voltage (I-V) characteristics, conductivity, ...

    • Linear and nonlinear dynamic conductivity of carbon nanotubes 

      Kamal, Marzuk M; Y evthshenko, Oleg M (BRAC University, 2005)
      Electronic properties of carbon nanotubes are studied. L inear response of dynamic conductivity of both zigzag and armchair nanotubes is analyzed at different temperatures and for different radii of nanotubes in the framework ...

    • Prospects of graphene and carbon nanotube for nanoscale interconnects 

      Rayhan, Md. Shakhawat Hossain; Uddin, Md. Shifat; Biva, Jannatul Tazrin; Huda, Md. Shofiqul (BRAC University, 2017-12)
      Interconnects are the channels that provide power and carry signals between various components on an integrated circuit. As technology is shrinking to nano scale the thickness of the interconnect wire is also decreasing. ...

    • Study of transfer free graphene formation 

      Roy, Sajib; Galib, O.F.M Abdul (BRAC University, 2012)
      The method of using CVD or Chemical Vapor Deposition [1-2] in the formation of graphene synthesis has recently progress quite a lot. The material shows exceptional electronic properties and also characterizes suspended ...

    • Vapor adsorption limitation of graphene nanoribbons in quasi conductance increment: a NEGF approach 

      Shakil, Shifur Rahman; Zohra, Fatema Tuz; Pramanik, Parna; Tushar, Raihanul Islam; Saha, Atanu Kumar; Bhuian, Md Belal Hossain (© 2015 Institute of Electrical and Electronics Engineers Inc., 2015)
      The adsorption of H2O molecules on Armchair Graphene Nanoribbons (A-GNR) was theoretically studied using Non Equilibrium Green Function (NEGF) formalism to determine Device Density of States (DDOS), Electrostatic Effective ...
