Surface nano science laboratory
Research Field
Dr. Pai received his education in physics from National Taiwan University (BSc) and University of Maryland, College Park (PhD). He conducted postdoc research in solid state division, oak ridge National Laboratory c/o Univ. of Knoxville. He later joined the center of condensed matter sciences, National Taiwan University, and is now a research fellow and a joint professor in physics. He is well recognized in his research field.
His expertise is in surface nano sciences and scanning probe microscopy, 2D materials surfaces, and the property-correlation at interface/surfaces.
Dr. Pai's laboratory conducts mostly scanning probe microscopy and spectroscopy to understand atom-resolved properties of surfaces. Other surface characterization techniques and theoretical investigation are also actively used.
The laboratory recently focuses on the properties of 2D materials crystals and their ultrathin films. mainly transition metal dichalcogenides. Our focus is to discover and study novel surface structures/phases, defects, intercalated structures, heterostructures, and properties (such as collelctive electronic ground states) in these materials from atomistic perspectives.
At present, the research topics are
- New structures and phases on 2D transitional metal dichalcogenides (TMD) surfaces and their properties.
- Controlled fabrication of defects, intercalation and heterostructures of 2D TMD materials and their properties.
- Intercalation (metals, alkalis) phenomena in 2D materials and 2D material heterostructures.
- charge density waves in low-dimension materials.

Job Description
Scanning tunneling microscopy of 2D transitional metal dichalcogenide heterostructured ultrathin films
The interns will use ultrahigh vacuum (UHV) scanning tunneling microscopy to examine the grown morphology and atomic scale details of 2D TMD heterostructured bilayer thin films. The focus of this position is to learn in-situ STM characterization of novel 2D materials.
Preferred Intern Educational Level
The applicants preferably have an education level in either MSc or PhD programs, and in fields of physics/chemistry/material science or related, and with a good academic standing.
Skill sets or Qualities
The internship involves heavy hands-on laboratory works. Therefore, applicants preferably have hands-on experiences in research laboratories. Knowledge and practical experiences in UHV, MBE, or STM are highly desirable though not required. The candidates should be highly motivated and diligent.
