Simulation of electronic properties of a quantum dot in transistor geometry at varying temperatures
(BRAC University, 2016-03)Electrical conduction is the ow of electron due to a force applied by an electric eld. In bulk material, conduction process obeys Ohm's law. The law states that current is proportional to applied voltage. But nano-sized ... -
Study of Titanium, Vanadium, Chromium and Manganese doped lead free double perovskites Cs2NaGaBr6 for potential solar cell
(Brac University, 2024-03)Lead-free inorganic double perovskites are making notable progress in the field of solar cells and optoelectronic devices. Promising materials such as Cs2NaGaBr6 are emerging as competitive alternatives. This research work ... -
Supersymmetric gauge theory: an application of group theory in high energy physics and starobinsky model of cosmological ination
(BRAC University, 2016)This thesis discusses the general role of symmetry in high-energy physics. It concentrates on the role of fermionic symmetry generators, which generate the symmetry known as supersymmetry. An extensive discussion of ... -
A two loop test of Matrix Big Bang Model
(Brac University, 2020-06)In this thesis we expand the effective action for the Matrix Big Bang presented in [9, 10] and indicate the interaction terms. Then we compute the two loop effective potential of this Matrix Big Bang model. We show that ...
