Pezone, R. (author), Baglioni, G. (author), Sarro, Pasqualina M (author), Steeneken, P.G. (author), Vollebregt, S. (author)A repeatable method to fabricate multi-layer graphene (ML-gr) membranes of 2r = 85 - 155 μm (t < 10 nm) with a 100% yield on 100 mm wafers is demonstrated. These membranes show higher sensitivity than a commercial MEMS-Mic combined with an area reduction of 10x. The process overcomes one of the main limitations when integrating graphene...conference paper 2023

(author), Sarro, Pasqualina M (author)Worlds first graphene-based Pirani pressure sensor is presented. Due to the decreased area and low thickness, the graphene-based Pirani pressure sensor allows for low power applications down to 0.9 mW. Using an innovative, transfer-free process, suspended graphene beams are realized. This allows for up to 100x miniaturization of the pressure...conference paper 2018

Vollebregt, S. (author), Dolleman, R.J. (author), van der Zant, H.S.J. (author), Steeneken, P.G. (author), Sarro, Pasqualina M (author)We present suspended graphene pressure sensors fabricated using an innovative surface micro-machining process. The great advantage of this process is that the molybdenum (Mo) catalyst layer for multi-layer graphene chemical vapor deposition (CVD) is also used as a sacrificial layer to suspend the graphene. This method allows for accurate control...conference paper 2017
