Sun, J. (author), Hu, D. (author), Liu, Zewen (author), Middelburg, L.M. (author), Vollebregt, S. (author), Sarro, Pasqualina M (author), Zhang, Kouchi (author)A micro-scale pressure sensor based on suspended AlGaN/GaN heterostructure is reported with non-linear sensitivity. By sealing the cavity, vacuum sensing at various temperatures was demonstrated. To validate the proposed concept of the AlGaN/GaN vacuum sensor, a 700 µm diameter circular membrane was electrically characterized under applied...journal article 2020

Zhang, B. (author), Wei, J. (author), Bottger, A.J. (author), van Zeijl, H.W. (author), Sarro, Pasqualina M (author), Zhang, Kouchi (author)We report the design, fabrication and experimental investigation of a MEMS micro-hotplate (MHP) for fast time-resolved X-ray diffraction (TRXRD) study of Cu nanoparticle paste (nanoCu paste) sintering process. The device and its system are designed to have a 60 ms minimum time interval, uniform temperature distribution and variant gas...conference paper 2019
