Treated Hfo2 Based Rram Devices With Ru, Tan, Tin As Top Electrode For In-Memory Computing Hardware, Yuvraj Dineshkumar Patel
Theses
The scalability and power efficiency of the conventional CMOS technology is steadily coming to a halt due to increasing problems and challenges in fabrication technology. Many non-volatile memory devices have emerged recently to meet the scaling challenges. Memory devices such as RRAMs or ReRAM (Resistive Random-Access Memory) have proved to be a promising candidate for analog in memory computing applications related to inference and learning in artificial intelligence. A RRAM cell has a MIM (Metal insulator metal) structure that exhibits reversible resistive switching on application of positive or negative voltage. But detailed studies on the power consumption, repeatability and retention …
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 …
Synthesis Of Novel Coo/Mnfe2o4 Heterostructured Nanoparticles And The Effects Of Variable Size And Extent Of Overgrowth On Their Magnetic Properties, Mohammad Tauhidul Islam
Synthesis Of Novel Coo/Mnfe2o4 Heterostructured Nanoparticles And The Effects Of Variable Size And Extent Of Overgrowth On Their Magnetic Properties, Mohammad Tauhidul Islam
MSU Graduate Theses
A combination of thermal decomposition and surfactant-assisted synthesis route was utilized to synthesize novel CoO/MnFe2O4 heterostructured nanoparticles. Four samples of varying CoO core size were synthesized with variable extent of overgrowth phase. XRD, XPS, SEM and TEM data show evidence of MnFe2O4 spinel phase overgrowth on CoO rock-salt structured nanoparticles. XPS and magnetic data reveal partial oxidation and formation of Co3O4 phase on 7 nm and 19 nm size CoO-based nanoparticles. The remaining samples having 22 nm and 34 nm dimensions show a higher percentage of FiM materials overgrowth on the …
Mxenes As Flow Electrodes For Capacitive Deionization Of Wastewater, Naqsh E. Mansoor
Mxenes As Flow Electrodes For Capacitive Deionization Of Wastewater, Naqsh E. Mansoor
Boise State University Theses and Dissertations
The energy-water nexus poses an integrated research challenge, while opening up an opportunity space for the development of energy efficient technologies for water remediation. Capacitive Deionization (CDI) is an upcoming reclamation technology that uses a small applied voltage applied across electrodes to electrophoretically remove dissolved ionic impurities from wastewater streams. Similar to a supercapacitor, the ions are stored in the electric double layer of the electrodes. Reversing the polarity of applied voltage enables recovery of the removed ionic impurities, allowing for recycling and reuse. Simultaneous materials recovery and water reclamation makes CDI energy efficient and resource conservative, with potential to …

Engineered Nanoparticles For Site-Specific Bioorthogonal Catalysis: Imaging And Therapy, Riddha Das
Doctoral Dissertations
Bioorthogonal catalysis offers a strategy for chemical transformations complementary to bioprocesses and has proven to be a powerful tool in biochemistry and medical sciences. Transition metal catalysts (TMCs) have emerged as a powerful tool to execute selective chemical transformations, however, lack of biocompatibility and stability limits their use in biological applications. Incorporation of TMCs into nanoparticle monolayers provides a versatile strategy for the generation of bioorthogonal nanocatalysts known as “nanozymes”. We have fabricated a family of nanozymes using gold nanoparticles (AuNPs) as scaffolds featuring diverse chemical functional groups for controlled localization of nanozymes in biological environments, providing unique strategies for …

Magnetism In Γ-Fesi2 Nanostructures: A First Principles Study, Sahil Dhoka
Dissertations, Master's Theses and Master's Reports
First-principles calculations are performed on γ-FeSi2 nanostructures grown on Si (111) and (001) substrate. An attempt to explain the origin of emergent magnetic properties of the metastable gamma phase of iron di-silicide (γ-FeSi2) is made, which show ferromagnetic behavior on nanoscale, unlike its possible bulk form. Many papers try to explain this magnetism from factors like bulk, epitaxial strain, interface, surface, edges, and corners but doesn’t provide an analytical study for these explanations. Density functional theory is used to analyze the magnetic effects of these factors. The results for the epitaxial structures show no magnetic behavior for …
