Improved Crystallinity of Annealed 0002 AlN Films on Sapphire Substrate
Comis Bersch, Bruno; Caminal Ros, Tomàs; Tollefsen, Vegard; Johannessen, Erik Andrew; Johannessen, Agne (Peer reviewed; Journal article, 2023)AlN is a piezoelectric material used in telecommunication applications due to its high surface acoustic wave (SAW) velocity, stability, and mechanical strength. Its performance is linked to film quality, and one method to ... -
Optimized DRIE process for different size membranes fabricated simultaneously
Tang, Jin (Master thesis, 2023)The rapid development of wireless communication systems raises the high demand for high Q factor resonators. To fabricate a high Q factor resonator, a precise membrane is important. It requires fabricating different sizes ... -
The Characterisation and Quantification of Immobilised Concanavalin A on Quartz Surfaces Based on The Competitive Binding to Glucose and Fluorescent Labelled Dextran
Hoang, Trinh Bich; Stokke, Bjørn Torger; Hanke, Ulrik; Johannessen, Agne; Johannessen, Erik Andrew (Journal article; Peer reviewed, 2019)The competition between various carbohydrates in the binding to Concanavalin A (Con A) can be exploited in gravimetric microsensors that detect changes in mass or viscoelasticity as a function of glucose concentration. ... -
The impact of area on BAW resonator performance and an approach to device miniaturization
Nguyen, Ngoc; Johannessen, Agne; Rooth, Stig; Hanke, Ulrik (Journal article; Peer reviewed, 2018)The dependence of the performance of thin film bulk acoustic resonator (FBAR) and solidly mounted resonator (SMR), on their areas is studied with the aid of finite element method (FEM) software. Dual step frame method is ...
