Starting off 2025, wrapping up Ph.D.
The time is coming to an end, with a very invigorating achievement at the end of my phd! I developed a technique which the NanoESCA spin detector can successfully and reliably acquire spin-resolved band structure! Here's a synopsis of a spin-polarized surface state from one of the known topological insulators, Bi2Se3. As I give this technique to my PI, LabMonti becomes one of a select few research groups capable of doing spin-resolved ARPES (SARPES) around the world!
Recognitions, Spring 2024
This year, I am teaching a senior year class (400B) with as a Distinguished Teaching Assistant! Also, I had a research trip to the ORNL and conducted another STM research. This research trip was gratefully supported by Carl S. Marvel Scholarship.
Second Publication in my Ph.D
A perspective paper is accepted by Applied Physics Letters! I helped curate data, make original figures, and reviewed the manuscript. This paper introduces readers to a core research idea that encompasses the LabMonti surface science part. DOI link will be posted soon.
I also applied to APS March 2024 meeting. Time to get my graduation ready, shake hands with people at the conference.
2023 Summer - STM research and NanoESCA
I'm grateful for the Carl S. Marvel travel grant award, I was able to take a trip to the ORNL and conducted very fascinating STM studies. Then the NanoESCA system is also giving me very interesting momentum microscope results. Stay tuned!
Also, I helped my advisor writing up a perspective paper on the Monti group's surface science ideas.
Synchrotron's RESPES-based paper will soon be published as well.
2023 Spring - A recognition
My research trip to ORNL is recognized by one of the travel grant award committee groups, so I am going to receive a Carl S. Marvel travel grant award!
2022 Fall Wrap up
I've gained more experience with lab skills - working on publications with novel findings in one of the quantum materials! I found a DFT collaborator to understand what can possibly be happening in my sample as I modified some atomic compositions. Also, a co-proposal with my advisor is accepted by one of the most pronounced national labs - Oak Ridge National Laboratories - for on-site use! This was announced a day before 2022 Christmas. Worth a long wait!
2022 Spring Wrap Up
Time flies and I'm already finishing my 4th year. In the meantime, I was able to observe very interesting phenomena with the materials that I've been jamming with. There are a lot of subsequent hypotheses I need to hash out, I'm hoping to speak out with a scientific paper. It is a little unfortunate to spend little time on stargazing nowadays, but I am happy with the progress I've made. Spoiler alert: NanoESCA will soon give its first debut and I'm proud of getting it commissioned by firsthand.
2021 Spring Wrap Up
The research group recently came back to 100% operation. I got a small cash prize from the university for being recognized as an excellent TA of the semester. I always try to devote myself where science is happening. I'm expecting a lot of ARPES experiments. I will make it count.
2020 Wrap up
This year has been quite insane - as we all know. I started to grow some 2D materials using CVD, a new instrument has been installed in the Monti lab (NanoESCA!), the group got a beam time at SLAC so we got a resonant Auger spectroscopic data. Things are going back up again yet overall its taking some time. Hope that we will have one less thing to worry in the next year - COVID. But whatever the circumstances I face, I'll keep up best of my efforts.
First paper at the UA!
As I participated with data analysis, I am on the author list! The paper was just accepted this August 2020.
Article accepted by ACS JPC C. My steam won't go cold.
A New Title!
As of May 29th 2020, I passed my comprehensive exam and became a Ph.D. candidate! This will be one of many!
I received 2020 Institute for Energy Solutions Summer Research Fellowship!
My summer research proposal has been accepted. This summer research grant will be spent for instrumentation of NanoESCA in the University of Arizona. I expect NanoESCA will be a strong analytical instrument for energy sciences!
My 2nd year is full steam ahead! (2019 Fall - 2020 Spring)
Working on data analysis, proposal, and experiment. One letter will soon be submitted. I passed 1st part of the comprehensive exams!
