Investigation of Structural, Electronic and Optical Properties of Silicon(Si) using DFT and TDDFT Thesis

Tagel, Admassu; Dr. Menberu, Mengesha; Mr. Edobus, Mosisa (2022-06)

Silicon is an indirect band gap semiconductor belonging to group III-V. It is commonly used in light emitting diodes (LED) and many optoelectronic devices fabrications. In this thesis, the structural, electronic and ...
Modeling Multi-Layer Thin Films (Mltf) In The Visible Ranges Of Electromagnetic Spectrum Using Transfer Matrix Method (Tmm) Thesis

Dr. Menberu, Mengesha; Dr. Girum, Abebe; Dr. Nebiyu, Gemechu (2023-03)

Multi-layer Thin-films are the stack of layer of material ranging from fractions of a nanometer to several micrometer in thickness. Therefore the intensity of light reflected off the surface of the material and transmitted ...
Structural And Electronic Properties Of Trisodium Antimonide With And With Out Considering Spin Orbit Coupling Thesis

Behailu, Mihiret; Dr. Menberu, Mengesha; Dr. Tolu, Biressa (2023-06)

Trisodium antimonide (Na3Sb) is a narrow band gap material and it is a binary compound crystallize in a hexagonal structure with the space group P 63/mmc. Since Na3Sb is the system with many electron it is a bit challenging ...
