Alloy design is still one of the most active fields of materials research to respond to the ever-changing needs of the modern global society. At the heart of designing new alloys is the knowledge of phase equilibria and the underlying thermodynamics. Most modern alloys have more than two or three components, but the phase diagrams for multicomponent systems either do not exist or are partially explored. We have developed a computational approach that can help fill this knowledge gap. Our Multi-Cell Monte Carlo (MC)² method allows, for the first time, the direct simulation of coexisting phases in many-component crystalline systems. It is universally applicable across materials classes and enables a wide range of applications.

There is a common perception that dislocations – topological line defects in crystals- are detrimental in functional materials as they degrade a group of devices’ functionality. On the other hand, recent studies have shown that these extended line defects exhibit unique and localized electronic and magnetic properties. 

We study the electronic structure of dislocations from first principles. In collaboration with the Myers group, we aim to show that dislocations in electronic and quantum materials can be utilized as active components in terms of functionality.

Specifically, we have shown that dislocations can act as 1D quantum wires in the diamond. Currently, we are examining the fundamental mechanisms for photoplasticity in group IV-VI semiconductors.

Note to Prospective Students:

Computational Materials Science is an interdisciplinary area. It’s a challenging mix of physics, materials science, mathematics, and computational science. While prior experience with computational work is not required (but encouraged), a strong background in math and materials science/physics is necessary for the type of work in our group.

If you are a graduate student at Ohio State, looking for a PhD mentor please contact Dr. Ghazisaeidi to set up a meeting. In addition to MSE, students from physics and other engineering programs are encouraged to apply.

Off-campus applicants should note that graduate admission and financial aid decisions are handled by the MSE department at Ohio State not by individual faculty. If you are not a student at Ohio State and are interested in applying, please visit the graduate application page.
