Postdoctoral Position in Advanced Light Source

This postdoctoral appointment is for the study of electronic properties of two dimensional materials and heterostructures and is under the direction of Prof. J. Katoch at Carnegie Mellon University (CMU). The postdoc will be based at the Advanced Light Source (ALS) in Berkeley, CA, and directly collaborate with scientists at CMU, The Ohio State University (OSU) and collaborators at ALS and elsewhere.

The successful candidate shall lead spectromicroscopy measurements at the Advanced Light Source under the supervision of Dr. E. Rotenberg and Dr. A. Bostwick, will work hand-in-hand with team members around the world for the design, fabrication, and measurement of two-dimensional heterostructure devices.

The goal of this position is to explore the electronic structure and many-body interactions of electrons in 2D heterostructure devices, having applied fields and currents. These effects are manifested in the electronic band structure, in the chemical bonds, or in the spin structure of materials, and in spatial inhomogenities of these properties. Measurements will be obtained using tools such as nanoprobe angular photoemission spectroscopy (nanoARPES), x-ray absorption spectroscopy, x-ray magnetic circular dichroism, and low energy electron microscopy combined with photoelectron emission microscopy (LEEM/PEEM). The postdoc is encouraged to incorporate other techniques (e.g. spectroscopy, scattering, or x-ray and electron transmission microscopy techniques) at ALS and the Molecular Foundry through collaborations and general user proposals.

The postdoc will plan and perform experiments and analyze data using state of the art tools as well as extend these capabilities as needed. The postdoc will attend scientific meetings, present results, and prepare publications to advance the field.
