Shin, D. (author), Kim, Hakseong (author), Kim, S.H. (author), Cheong, Hyeonsik (author), Steeneken, P.G. (author), Joo, C. (author), Lee, Sang Wook (author)The inherent properties of 2D materials—light mass, high out-of-plane flexibility, and large surface area—promise great potential for precise and accurate nanomechanical mass sensing, but their application is often hampered by surface contamination. Here we demonstrate a tri-layer graphene nanomechanical resonant mass sensor with sub-attogram...journal article 2023

Park, S.Y. (author), Newton, C.E.L. (author), Lee, Rachel (author)The sudden adoption of working from home (WFH) during the COVID-19 pandemic has required the reconfiguration of home spaces to fit space for remote work into existing spaces already filled with other domestic functions. This resulted in blurring of home and work boundaries, the potential lack of space for telecommuting from home, and...journal article 2023

(author), van der Zant, H.S.J. (author)The temperature dependent order parameter provides important information on the nature of magnetism. Using traditional methods to study this parameter in two-dimensional (2D) magnets remains difficult, however, particularly for insulating antiferromagnetic (AF) compounds. Here, we show that its temperature dependence in AF MPS<sub>3</sub> (M...journal article 2023

Lee, J. (author), Theuwissen, A.J.P.A.M. (author)This paper presents a new 2-step SAR ADC architecture for image sensors in machine vision applications. This structure effectively improves the structural problems of the image sensor caused by the area occupied by the ADC, such as linearity and temporal noise performance. In this work, we designed a two-step SAR ADC using a 6-bit SAR ADC and...conference paper 2023
