Job Opening (Post. Doc)
◈ Postdoctoral positions (one or two) are available in Opto-Device Lab. (http://optodevice.gist.ac.kr) for innovative research on heat manipulation technologies in nanoscale materials, optoelectronics and quantum devices. If the candidate has postdoc experience with high quality track records, he/she will be invited as a research professor in the school.
◈ Research Overview and Area: The quantum efficiency of optoelectronics devices and the speed of the electronic devices are limited by the generation of heat in response to external electric fields and the loss of energy. In solids, heat manifests as a broad vibrational spectrum of atoms in the 1 GHz–100 THz range and is quantized as phonons (optical phonons: 1–100 THz; acoustic phonons: < 1 THz). Compared to the frequency bands used by photonics (> 100 THz) and electronics (< 100 GHz), the phonon spectrum is suitable and yet to be developed for safe and precise medical imaging and faster communications. As a limited example of applications, surface acoustic waves (SAW: 1 – 3 GHz) are used in sensors for mobile communications; in contrast, the high-frequency phonon band (frequency: 10 GHz – 100 THz) has yet to be exploited. Therefore, not only as a means of utilizing waste heat but also as a basis for implementing devices in an unexplored frequency range, phononics is set to be one of the most important areas for emerging technologies in the current era in which energy sustainability is demanded.
Under the support from Samsung Future Technology Program and other funding agencies, we are conceptualizing/developing functionalized materials and devices in terms of heat wave manipulations. The successful candidate should be provided with detailed project description and methodologies from PI. Once hired, the successful candidate is expected to perform independent experimental research in this area and carry out collaborative research with the existing members of opto-device Lab., as yearly guided by the project description.
◈ Qualifications: Especially, we are seeking one experimental researcher and one theorist who have experience at least on one of the following tools:
● optical properties of meso-/nanostructures, which can be extended to phononics via this project
● electrical transport, which can be extended to thermal transport via this project
● nanoscale microscopy (e.g., near-field scanning derivatives, two-photon microscopies, confocal microscopy etc.)
● Infrared and mid-infrared spectroscopies
◈ Facilities: Opto-device Lab. is equipped with state-of-the-art optics facilities, such as PL, PLE, Absorption, Deep-Level Transient Spectroscopy, Pump-Probe Derivatives (measuring transient carrier/phonon dynamics & heat transfer and various carrier-light interactions), Time-resolved PL, THz spectroscopy (emission, reflection, absorption in various geometries), THz Spectrometer with Tunable High Power THz Lasers, THz 2D Imaging, and Nanoscale 2D Imaging. We also co-operate fabrication and growth facilities in the department, including MOCVD, ICP-RIE, RTA, and E-beam evaporation tools.
◈ Salary and Job Function
1. Salary: 3500~5000 (x10k Korean won) depending on the track records.
2. Job Function: 1) Experimentalist: Performing laser-based experiments regarding detection and control of phononic properties in quantum structures; Conceptualization and characterizations of novel phononic materials and devices; Operations of the relevant equipment’s. 2) Theorist: Performing the theoretical calculations on phonon amplifications, switching, scatterings at the interfaces, and electro-magnetic conversion in quantum structures.
