Kinetic Monte Carlo Investigations Involving Atomic Layer Deposition Of Metal-Oxide Thinfilms, David Tyler Magness
Kinetic Monte Carlo Investigations Involving Atomic Layer Deposition Of Metal-Oxide Thinfilms, David Tyler Magness
MSU Graduate Theses
Atomic Layer Deposition is a method of manufacturing thin film materials. Metal-oxides such as zinc-oxide and aluminum-oxide are particularly interesting candidates for use in microelectronic devices such as tunnel junction barriers, transistors, Schottky diodes, and more. By adopting a 3D Kinetic Monte Carlo model capable of simulating ZnO deposition, the effect of parameters including deposition temperature, chamber pressure, and composition of the initial substrate at the beginning of deposition can be investigated. This code generates two random numbers: One is used to select a chemical reaction to occur from a list of all possible reactions and the second is used …
Heterostructure Of 2d Materials: Hfs2/Hfo2/Si, Christopher J. Robledo
Heterostructure Of 2d Materials: Hfs2/Hfo2/Si, Christopher J. Robledo
MSU Graduate Theses
Heterostructures have been utilized in electronic devices for over 50 years with the proposal for the first heterostructure transistor in 1957. With the scaling of devices, it is necessary to create new heterostructures that will comply with Moore’s Law, as well as make devices faster and consume less power. Novel 2D materials, such as hafnium disulfide, have shown promise as an active channel layer, while hafnium dioxide is already proven to be a replacement of silicon dioxide for the gate insulating layer. However, fabrication techniques for wide-scale integration of these heterostructures have not yet been achieved. Also, the dielectric properties …
Synthesis And Characterization Of Carbon Coated Barium Titanate Core-Shell Nanoparticles, Moudip Nandi
Synthesis And Characterization Of Carbon Coated Barium Titanate Core-Shell Nanoparticles, Moudip Nandi
MSU Graduate Theses
Core-shell nanoparticles (CSNP) with fascinating ferroelectric properties have diverse applications in biotechnology and the electronic field of studies. Among so many perovskites, barium titanate (BTO) nanoparticles draw much interest due to their distinct electronic and ferroelectric features. Additionally, the incorporation of carbon in the shell of CSNP makes it suitable for application in many fields due to its innocuous nature. Carbon not only increases the biocompatible properties of an element but also gives mechanical stability to the CSNP. This thesis is targeted towards the synthesis of oxide-carbide CSNP, where the core is made of BTO and the shell is made …
Performance Of Pld Grown Zno Thin Film As A Thin Film Transistor, Shahidul Asif
Performance Of Pld Grown Zno Thin Film As A Thin Film Transistor, Shahidul Asif
MSU Graduate Theses
The performance of ZnO thin film (grown in different parameters) as a thin film transistor (TFT) is the focus of this study. ZnO is renowned for being n-type semiconductor naturally which was utilized in fabricating a thin film transistor here. This thesis is compared the performance of ZnO thin film transistor by growing the thin film using pulsed laser deposition (PLD) on two slightly different substrates at different temperatures in an optimal 0.1 milli bar oxygen pressure which was later analyzed using other material characterization methods. The substrates were both Si (100) but had different resistivity due to different amount …

Investigation Of Mnxni1-Xo Thin Films Using Pulsed Laser Deposition, Md Ashif Anwar
MSU Graduate Theses
The exchange bias (EB) effect, especially in nanomaterials, is highly promising for use in antiferromagnet-based spintronics applications. NiO is a well known antiferromagnetic material with a high Néel temperature (525K) and can exhibit ferromagnetism/ ferrimagnetism by adding other magnetic transition elements. Our previous work has shown that the antiferromagnetic characteristics of conventional NiO insulating nanostructured material can be altered to have substantial ferrimagnetic characteristics by doping NiO with Mn or Co. Pulsed laser deposition (PLD) was used to grow heterostructures comprised of a nanostructured thin NiO film deposited on the surface of a MgO (100) and Al2O3 …
