We are pleased to announce that our latest collaborative research with Prof. Byungjo Kim, Prof. Joonki Suh, and Prof. Hyun Seok Lee has been published in Small!
Preventing Plasma-Induced Resist Hardening in Molybdenum Disulfide Transistors via Sacrificial Metal Mask Lithography
This work reveals the atomistic origin of plasma-hardened photoresist residues on MoSβ and introduces a sacrificial Au mask process that prevents interfacial contamination. The method reduces contact resistance by approximately tenfold, enhances ON-current by an order of magnitude, and is applicable to photolithography, electron-beam lithography, top-gated devices, with flake, MOCVD-grown and ALD-grown MoSβ.
Congratulations to the first author, Dahyeon Kim, and all co-authors!

We are excited to share our new paper in Advanced Functional Materials: "Thermally Robust Polymer-Based Analogue Switch for Flexible mmWave Application."
In partnership with Prof. Min-Ju Kim (Dankook University), our team has overcome the historic thermal limitations of organic materials. By leveraging iCVD-deposited pV3D3, we have engineered a flexible RF switch that delivers robust performance for next-generation mmWave applications.
Kudos to lead researchers Sungmoon and Changwoo for their outstanding work on this project!π₯³ππ

Our new paper is out in ACS Applied Materials & Interfaces! π’
We developed a polarity engineering technique for MoTe2 to create homogeneous complementary circuits on a single flake. By combining molecular adsorption and e-beam irradiation, we successfully demonstrated high-gain inverters, NAND/NOR gates, and even reversible circuit function switching.
A massive well done to Seungchan for this outstanding research! π₯³ππ

Our new paper on energy-efficient RF switches is now published in Advanced Science! We developed a VOx-based non-volatile switch that requires zero power to maintain its state, tackling a major hurdle for next-gen 5G/6G devices.
We demonstrated its potential by building a tunable RF filter, showcasing a new path for reconfigurable communication systems.
Huge congratulations to the amazing first authors, Dabin and Dahyeon, for leading this incredible work! π₯³ππ
