Bandstru cture observation of graphene nanoribb on and boron-nitride nanoribbon embedded graphene nanoribbon
(BRAC University, 2016-04)Due to distinctive electronic properties and potential future application in tunable bandgap opening, Graphene Nanoribbon (GNR) has apprehended strong attention. Boron Nitride Nanoribbons (BNNR) exhibit analogous structure. ... -
I-V characteristics observation of graphene boron nitride vertical heterojunction van der waals resonant tunneling diode
(BRAC University, 2016-08-17)In this paper, we are going to observe the band structure and I-V characteristics of Graphene Boron Nitride Vertical Heterojunction Van der Waals Resonant Tunneling Diode. Furthermore, showing negative differential resistance ... -
Simulation based study of non-planar multigate indium gallium arsenide quantum well field effect transistors
(BRAC University, 2015-07)QWFETs with non-planar, multigate structures are known to provide higher electrostatistics than their conventional planar counterparts. Due to this desirable feature of the non-planar, multigate architecture, the electronics ... -
Time-independent schrodinger-poisson coupled simulation based study of InP and InAlAs quantum well field effect transistors
(BRAC University, 2016)The electronics industry first started appreciating QWFETs over MOSFETs back in late 2011 due the QWFET’s unique wrapped gate around channel structure, which provided better control over threshold voltage and reduced ... -
Transition in electronic transport properties of graphene nanoribbon due to the adsorption of atoms and molecules
(© 2015 Institute of Electrical and Electronics Engineers Inc., 2015)The adsorption effects of gas molecules on semiconducting armchair graphene nanoribbon (A-GNR) are studied considering on the significant changes over current-voltage characteristics, device density of states and electrostatic ... -
Vapor adsorption limitation of graphene nanoribbons in quasi conductance increment: a NEGF approach
(© 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 ...
