Tung Lab
Machine-translated · View original
A lab that approaches atomically thin two-dimensional semiconductors from crystal growth through to manufacturing.
AboutAbout the lab
Chemical System Engineering for Semiconductor Manufacturing
The Tung Lab researches how to turn two-dimensional materials, extremely thin materials made of atomic layers, into technologies that can actually be used.
By gaining a deep understanding of epitaxy, a method of growing crystals, the lab investigates how materials grow on a substrate and finely controls their synthesis.
The lab creates new p-type two-dimensional semiconductors, expanding the range of materials available for atomically thin devices.
Drawing on chemical engineering principles, the lab aims to develop guidelines for designing semiconductor materials, interfaces, and manufacturing processes.
Key terms
- Two-dimensional materials
- Sheet-like, extremely thin crystalline materials made of just one to a few atomic layers
- Epitaxy
- A method of growing a new crystal layer with a matching orientation on top of a crystalline substrate
- p-type semiconductor
- A semiconductor in which holes (places where an electron is missing) carry the current. It is combined with n-type semiconductors, in which electrons carry the current, to build circuits

ResearchResearch themes
The lab studies how to grow materials that are only one atom thick, how to connect them to electrodes, and how to integrate them. By combining materials chemistry, epitaxy, interface science, and device engineering, the lab aims to build a pathway that links atomic structure to the behavior of electrons.
*Illustrative imageWafer-Scale Growth of Two-Dimensional Semiconductors
Focusing on transition metal dichalcogenides, the lab develops methods to grow them across entire wafers with uniform crystal orientation and thickness. It is also exploring ways to build them directly into devices without transfer.
*Illustrative imagep-Type Materials Grown Directly on Insulating Films
Two-dimensional electronic circuits lack p-type materials. The lab explores methods to synthesize them directly on amorphous (non-crystalline) insulating films, without using a single-crystal substrate.
*Illustrative imageElectrode and Interface Design
The lab investigates how the boundaries with metal electrodes and surrounding insulators affect the flow of electricity. It works on making electrodes with low contact resistance and on chemical control of interfaces.
*Illustrative image3D Integration and Hardware for AI
Toward 3D integration, in which thin materials are stacked vertically, the lab studies low-temperature growth and assembly methods that do not require transfer.
