Our STM is here!
We are excited to get our 300mK 15T UHV STM installed.
The table/chamber is heavy! Thanks Jason for helping us move it to the lab.
The table to be united with the cryostat.

How often one get to see this?
New Oxford ProteoxMX dilution fridge being installed. Reached 8.75mK on MC.
Liu group receive New Frontier Grant
We are excited to receive the New Frontier Grant from Cornell College of Arts & Sciences. The New Frontier Grants program aims to enable novel, high-risk/high-impact research projects with compelling visions for transformative advances in the arts and humanities, social sciences, and natural sciences. In this projects, we aim to develop a high energy- and spatial-resolution spin sensor to uncover hidden magnetic orders with zero global magnetization, such as Skyrmion lattices and quantum spin liquids. This unique single spin microscope will be enabled by combining scanning tunneling microscope (STM) with recently emerged van der Waals materials and devices. With this technique, we will be able to visualize spin textures and probe spin excitations.
This two year funding will support our early stage effort in developing this new technique. We very much appreciate the support from Cornell A&S and donors who made this program possible.

First device
From exfoliation, stacking, to nano-fabrication, we have established the pipeline for creating vdW devices. This marks a mile stone—achieving one of the key technical pillars of the lab.
Device created by Chang Chang
First stack made!
Chang Chang made the first stack of the lab! It is a simple BN-graphene-BN but it only going to get better and more sophisticated from here.
We are looking for new members!
This is an exciting time to join our team as our lab takes shape. You'll have the unique opportunity to explore the depths of experimental physics, involving tasks like setting up a dilution fridge, adapting data acquisition programs and interfacing them with instruments, and customizing STM for 2D material samples. This experience will provide you with a comprehensive understanding of condensed matter experiments and enhance your problem-solving skills.
Considering the relatively short setup timeline, your contributions will undoubtedly be rewarding, and you'll embark on exciting projects right from the beginning. As one of the founding members of our group, you'll collaborate closely with the PI and have the opportunity to shape the group's culture and direction.
If these prospects align with your interests and aspirations, we encourage you to explore our opportunity page and reach out without hesitation.
Liu Lab is Launched at Cornell
It all begins with an idea.
On August 1, 2023, I started on my journey at Cornell University—an incredibly supportive, stimulating, and beautiful place. As of now, we have placed orders for all major pieces of equipment, including the Unisoku USM 1300 STM and the Oxford Proteox dilution fridge, among others. Lab renovation is in progress, with the expectation of gaining the capability to fabricate van der Waals (vdW) samples at the beginning of 2024. And we anticipate the completion of the dilution fridge and STM installation in the latter half of 2024.
We looking forward to the completion of our lab and beginning our experiments. Today, we are thrilled to launch our lab website, and I invite you to stay tuned for the exciting results we will be sharing in the near future.
