Autor: Malkolm Hinnemo, Patrik Ahlberg, Zhibin Zhang, Shi-Li Zhang, Jörgen Olsson, Asta Makaraviciute, Zhen Zhang

Publikováno v: IEEE Sensors Journal. 18:6497-6503

Sensing biomolecules in electrolytes of high ionic strength has been a difficult challenge for field-effect transistor-based sensors. Here, we present a graphene-based transistor sensor that is capable of detection of antibodies against protein p53 i

On Monolayer Formation of Pyrenebutyric Acid on Graphene

Autor: Carl Hägglund, Jie Zhao, Viktor Djurberg, Patrik Ahlberg, Shi-Li Zhang, Malkolm Hinnemo, Zhibin Zhang, Ralph H. Scheicher

Publikováno v: Langmuir. 33:3588-3593

As a two-dimensional material with high charge carrier mobility, graphene may offer ultrahigh sensitivity in biosensing. To realize this, the first step is to functionalize the graphene. This is commonly done by using 1-pyrenebutyric acid (PBA) as a

Scalable residue-free graphene for surface-enhanced Raman scattering

Autor: Wencai Ren, Patrik Ahlberg, Malkolm Hinnemo, Shi-Li Zhang, Zhibin Zhang, Hui-Ming Cheng, Carl Hägglund

Publikováno v: Carbon. 98:567-571

A room-temperature polymer-assisted transfer process is developed for large-area, single-layer graphene grown by means of chemical vapor deposition (CVD). This process leads to transferred graphene layers free of polymer contamination. The absence of

Interface Dependent Effective Mobility in Graphene Field Effect Transistors

Autor: Patrik Ahlberg, Jörgen Olsson, Shi-Li Zhang, Malkolm Hinnemo

By pretreating the substrate of a graphene field-effect transistor (G-FET), a stable unipolar transfer characteristic, instead of the typical V-shape ambipolar behavior, has been demonstrated. This behavior is achieved through functionalization of th

Field operational testing for safety improvement of freight trains using wireless monitoring by sensor network

Autor: Anders Rydberg, Filip Zherdev, Lennart Andersson, Mathias Gruden, Dragos Dancila, Malkolm Hinnemo, Nils Edvinsson, Roger Byström, Kjell Brunberg

Publikováno v: IET Wireless Sensor Systems. 4:54-60

Today, the majority of wagon failures on railroad systems are because of the poor maintenance of ball bearings, which causes emergent stops and delays. The existing stationary detectors, lack in predicting failures which cause troubles in scheduling

A two-in-one process for reliable graphene transistors processed with photolithography

Autor: Shi-Li Zhang, Malkolm Hinnemo, Man Song, Jörgen Olsson, Patrik Ahlberg, Xindong Gao, Zhibin Zhang

Research on graphene field-effect transistors (GFETs) has mainly relied on devices fabricated using electron-beam lithography for pattern generation, a method that has known problems with polymer contaminants. GFETs fabricated via photo-lithography s
