Pulsed Laser Annealing On The Optoelectronic Properties Of Zno Thin Films, Md Abu Zobair
Pulsed Laser Annealing On The Optoelectronic Properties Of Zno Thin Films, Md Abu Zobair
MSU Graduate Theses
ZnO thin films have attracted great attention recently due to their unique electronic and optical properties. However, for proper implementation of ZnO in electronic devices it is necessary to understand the role of native point defects present inside the material as these wide bandgap semiconductors are inherently n-type due to oxygen vacancies. The objective is to control the electronic and optical properties of ZnO thin films through pulsed laser annealing (PLA). Thin films of ZnO have been grown on different substrates using pulsed laser deposition. Then PLA of the films are done by changing laser parameters (energy, frequency, pulse width, …
Study Of Nano-Bio Interfaces In Nano-Bio Conjugates: Nanoparticles Of Zinc Oxide (Zno) And Biomolecules Of Glucose, Cytosine, And Thymine, Bithi Paul
MSU Graduate Theses
Nano conjugates, composites of inorganic nanomaterials and bio molecules such as DNA, RNA and proteins, establish a sequence of wide varieties of nano-bio boundaries. The formation of these boundaries strongly depends on bio physicochemical reaction of biomolecules coated on the surface of nanomaterials. I am investigating various nano-bio conjugates consisting of zinc oxide (ZnO) nanoparticles with simple biomolecules including glucose and the nitrogenous bases of DNA such as cytosine and thymine. All nano-bio conjugates were fabricated using a standard bio-chemical synthesis process. Structural, physical, bio-chemical interface properties of nano-bio composites were probed using X-ray diffraction (XRD), Raman spectroscopy, and photoluminescence …
