Research Interests

My research interests focus on first-principles calculations based on density functional theory. The objective is to design new spintronic materials by using first principles codes. In particular, materials exhibit half metallic properties. A half metal shows metallic properties in one of the electronic spin channel and semiconducting behaviors in the oppositely oriented spin channel. The feature is that the current of a half metal is 100% spin polarized. They can be utilized for information storage and transmission. To use the designed materials for device applications, it is necessary to check the stability. This is done by calculate the relations of frequency and momentum, inverse of the wave length for vibrational modes, the phonon dispersions. Therefore, the design of such materials, one should have the basic understanding of quantum mechanics for electrons, phonons and even the so-called magnons, since spin moments are involved and good physical intuitions about how electrons and their spin moments and ions interact. This is exemplified in my co-authored book, ‘Half-metallic materials and their properties’ published many experimental and theoretical methods using physical pictures.
