Due to the large number of posts recently, there is currently a delay of several weeks between posts being submitted and the corresponding emails being distributed to all users. Please bear with us while we try to improve this. In the meantime – and until this notice is removed – it would assist us considerably if you could submit only important and/or urgent posts and thus help to reduce the size of the mail queue. Under no circumstances should you resend posts multiple times when you find the emails are not distributed immediately.
In light of the Russian military offensive in Ukraine, we request that announcements relating to events, jobs and other activities associated with institutions supported by the Russian and Belarusian states are not posted to the Psi-k forum.

Project title: “Development of an accurate atomic-level TCAD approach by introducing the localized orbital scaling correction scheme into multi-space density functional theory”
Prof. Yong-Hoon Kim at Korea Advanced Institute of Science and Technology (KAIST) and Prof. Weitao Yang at Duke University are inviting applications for a postdoctoral position in DFT method development. The successful candidate will be based in the group of Prof. Yong-Hoon Kim at KAIST Daejeon-Korea and has the opportunity to visit Prof. Weitao Yang’s group at Duke University Durham-USA on a regular basis.
The objective of the project is to implement the localized orbital scaling correction (LOSC) scheme developed by Prof. Yang’s group [1] into the SIESTA package in which the multi-space constrained-search DFT (MS-DFT) formalism developed by Prof. Kim’s group has been already implemented [2]. MS-DFT is established by replacing the Landauer picture with the ansatz of mapping the finite-bias quantum electron transport process to the drain-to-source optical electronic excitation counterpart and carrying out a multi-space constrained-search procedure. Unlike the standard DFT-based nonequilibrium Green’s function (NEGF) approach, MS-DFT provides a rigorous ground to carry out ab initio quantum transport calculations based on orbital-based advanced exchange-correlation energy functionals. In this project, the successful candidate will work on the implementation of the periodic LOSC scheme within SIESTA, thereby enabling LOSC-based MS-DFT calculations. Because the LOSC approach provides both accurate total energies and eigenvalue spectra, MS-DFT calculations based on LOSC are expected to allow highly accurate device/process technology computer-aided design (TCAD) simulations. She/he will then apply the developed atomic-level TCAD software to the study of scientifically important and/or technologically promising nanoscale devices. The specific application target will be determined based on the background and interests of the candidate.
