Postdoc/Scientist - Time Resolved Photoemission Electron Microscopy
Postion Description: The Femtosecond Spectroscopy Unit at OIST is recruiting postdoctoral or research scientist candidates in the broad field of ‘time resolved photoemission microscopy and spectroscopy of novel materials’. Over the past five years, the unit has developed pioneering capabilities to image spatio-temporal phenomena with nanometer- and femtosecond-scale resolution in semiconductor structures, thereby making movies of photocarrier transport driven by spatial bandstructure variations , or by intensity variations in tailored optical pulses . The unit now seeks to extend these studies to exploring high resolution spatio-temporal phenomena in new emerging materials, such as van der Waals heterostructures, quantum materials and topological insulators.
The unit’s experimental facilities include state-of-the-art laboratories with multiple kHz, 100-kHz and MHz class amplified, ultrafast lasers, multiple ultrafast oscillator systems, a low-energy electron microscope and photoemission electron microscope (LEEM/PEEM), time-of-flight based Momentum Microscope (METIS-TOF) and a 17 T cryo-free superconducting magnet for nonlinear optical & THz measurements. First-rate shared institute facilities for nanofabrication and characterization are also available.
Interaction opportunities exist with various international institutes, including Stanford Univ. (California, USA), Rice Univ. (Houston, Texas, USA), École Normale Supérieure (Paris, France), TIFR (Mumbai, India) and Univ. of Cambridge (UK). Generous funding to present research results at international conferences is also available.
Qualifications: Applicants are expected to have a PhD in the broad areas of experimental condensed matter physics, materials physics or a related field. Experience in ultrafast spectroscopy or photoemission spectroscopy is essential. Knowledge of van der Waals heterostructures, correlated or topological materials will be an advantage. Conversion to a long term position is a possibility.
Compensation and Benefits: In line with the values at OIST we are committed to attracting top-class researchers from across the world, and to ensuring a supportive, creative and productive atmosphere for them and their families. The final compensation package will take into consideration the candidates’ experience and background and will be competitive with international standards.
Application Instructions: Please submit (i) a cover letter (<1 page), stating your motivation to apply, (ii) your CV including publication list, and (iii) contact information of at least two references to recruiting-FSU@oist.jp. Short listed candidates may be invited for an interview to OIST. Applications will be reviewed as received.
