Major achievements:

1. Discovered a "dynamic swapping mechanism", which is critical to achieve atomic-scale control of the interface structure [Nature Materials 13, 879 (2014)]. It was found that during the epitaxial growth of metastable materials, the molecular components of a later deposited atomic layer can dynamically switch position with a previously deposited atomic layer during the growth and thus induce an unexpected growth of a later-deposited atomic layer below a previously-deposited atomic layer. We identified the underlying thermodynamic driving force and dynamic mechanism, proposed a revised growth strategy, and revealed the generality of the phenomenon in other materials. The predictions were perfectly confirmed by our experimental collaborators, and later by other groups with different growth techniques [Appl. Phys. Lett. 106, 131601 (2015)] and in different materials [Phys. Rev. B 92, 035415 (2015)].

2. Discovered a general phenomenon during the dynamic processes in semiconductors and insulators: a rate-limiting transition state is usually located on the energy surface of an excited initial state rather than the ground initial state, the latter of which was typically assumed [NPG Asia Materials 10, 45 (2018)]. The activation barrier calculation based on the traditional assumption can sometimes induce significant errors, e.g. hopping of carbon vacancy in silicon carbide. A straightforward method to estimate the error bars by the traditional assumption was proposed and new computational procedures of activation barriers were provided. Predictions based on the findings in this work are in excellent agreement with highly-accurate experimental results.

3. Provided in-depth understanding on the point defects and grain boundaries in several functional materials: identified their atomic structures, stabilities, electronic properties, relationship with experimental conditions, and methods to tune the defects [Advanced Materials 31, 1805047 (2019); NPG Asia Materials 9, e345 (2017)].

4. Predicted the structure-electronic properties, band alignments, IR/Raman spectrum, and optical absorption spectrum for a number of carbon nanomaterials and III-V semiconductors, and provided favorable insights into their structure characterization and applications in electronic and optoelectronic devices [Appl. Phys. Lett. 109, 112104 (2016); J. Phys. Chem. C 117, 13072 (2013); Phys. Rev. B 84, 075439 (2011); J. Phys. Chem. C 115, 24463 (2011); J. Phys. Chem. C 114, 6959 (2010)].

Open position of Postdoctoral Researcher

Professor Guangfu Luo's Computational Materials Design group at the Southern University of Science and Technology (SUSTech), Shenzhen, China has been working on computational modeling of functional materials using first-principles methods, including density functional theory and many-body quantum theory. Currently, one postdoctoral position is available, with projects involving computational modeling of the electronic properties, optical properties, defects, and growth dynamics of semiconductors and clean-energy materials.

A PhD degree in a relevant field (e.g. materials science or condensed matter physics) and familiarity with typical DFT codes (e.g. VASP or Quantum Espresso) are required. The research will broadly develop computational modeling skills and have opportunities to work closely with superior experimental groups. The appointment is initially for one year and can be extended based on mutual agreement. Depending on performance, the salary varies between 300,000 and 330,000 RMB/yr.

Interested applicants should send a cover letter and CV to luogf[at]sustech.edu.cn. Review will begin immediately and continue until the positions are filled.
