Congratulations to IMG Member Sunghyun Hwang and IMG Professor Yong-Kyu Yoon , on their recent publication in the journal IEEE Photonics Technology Letters! In this work, titled, “Silicon Phononic Nanowires Enable Ultra-Low Thermal Conductivity Measured by Raman Spectroscopy”, a novel device structure and precise measurement technique were introduced to assess the thermal conductivity of PnC-supported Si MEMS pixels using vacuum-based Raman spectroscopy. The study revealed remarkably low thermal conductivity in PnC-integrated Si nanowires, with values as low as 1.1W/(m×K) reported successfully.

Congratulations to IMG Professor, Dr. Xin Tang, and IMG Members, Keming Li, Miao Huang, and Chenyu Liang, on their recent publication in the journal Oncogene! This work, titled “Biophysics in tumor growth and progression: from single mechano-sensitive molecules to mechanomedicine”, highlights cancer mechanics ranging from molecular and cellular level to tissue level and clarifies functional crosstalk between mechanotransduction and oncogenic signaling. This pioneering work paves the new ways to leverage the anomalous physical alterations in human tumors as new therapeutic targets for next-generation cancer mechanomedicine.

Congratulations to Dr. Tabrizian and IMG Students Faysal Hakim and Troy Tharpe on their recent publication in Nature Electronics! Titled, "A ferroelectric-gate fin microwave acoustic spectral processor," this groundbreaking work showcases UF Research Service Center's world-class capabilities in realizing super-complex devices comparable to state-of-the-art transistors. Read more about it here:

An acoustic resonator that uses a three-dimensional silicon fin and an atomic-layered hafnia-zirconia ferroelectric transducer can be integrated into chip-scale filter arrays to make adaptive switch-free spectral processors for wireless communication.

At the IEEE International Electron Devices Meeting (IEDM) 2023 taking place in San Francisco, CA this week, ECE Florida Ph.D. student S M Enamul Hoque Yousuf, along with his advisor Prof. Philip Feng, reports on a new advancement in “More-than-Moore” devices using atomically thin semiconductors. In the paper ( #17.4), the UF ECE group describes the demonstration of high-performance monolayer and bilayer MoS2 vibrating channel transistors (VCTs), which, for the first time, transduce the radio-frequency sub-nanometer-scale motions of semiconductor VCTs by directly reading out the small-signal drain-source current, without having to rely on a frequency-conversion or mixing circuit.

Congratulations to UF ECE and IMG Ph.D. student Tahmid Kaisar, S M Enamul Haque Yousuf, and Prof. Philip Feng, and their collaborators (Dr. Mina Rais-Zadeh at NASA JPL, and Dr. Soumyajit Mandal at Brookhaven National Lab), on their recent journal publication in IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, titled “Five Low-Noise Stable Oscillators Referenced to the Same Multimode AlN/Si MEMS Resonator.” In this paper, the authors report on the first experimental demonstration of five self-sustaining feedback oscillators referenced to a single multimode resonator, using piezoelectric aluminum nitride on silicon (AlN/Si) microelectromechanical systems (MEMS) technology. Integrated piezoelectric transduction enables efficient readout of five resonance modes of the same AlN/Si MEMS resonator, at 10MHz, 30MHz, 65MHz, 95MHz, and 233MHz with quality (Q) factors of 18600, 4350, 4230, 2630, and 2138, respectively. Five stable self-sustaining oscillators are built, each referenced to one of these high- Q modes, and their mode-dependent phase noise and frequency stability (Allan deviation) are measured and analyzed. The five oscillators’ overall promising performance also suggests suitability for multimode resonant sensing and tracking. This work elucidates mode dependency in oscillator noise and stability, one of the key attributes of mode-engineerable resonators. Paper link: https://doi.org/10.1109/TUFFC.2023.3312159
