Optomechanical methodology for characterizing the thermal properties of 2D materials
Hanqing Liu, Hatem Brahmi, Carla Boix-Constant +3
Heat transport in two-dimensions is fundamentally different from that in three dimensions. As a consequence, the thermal properties of 2D materials are of great interest, both from…
Nanomechanical resonators fabricated by atomic layer deposition on suspended 2D materials
Hanqing Liu, Saravana B. Basuvalingam, Saurabh Lodha +4
Atomic layer deposition (ALD), a layer-by-layer controlled method to synthesize ultrathin materials, provides various merits over other techniques such as precise thickness control…
Ultra-sensitive graphene membranes for microphone applications
Gabriele Baglioni, Roberto Pezone, Sten Vollebregt +8
Microphones exploit the motion of suspended membranes to detect sound waves. Since the microphone performance can be improved by reducing the thickness and mass of its sensing memb…
Drawing WS2 thermal sensors on paper substrates
Martin Lee, Ali Mazaheri, Herre S. J. van der Zant +2
Paper based thermoresistive sensors are fabricated by rubbing WS2 powder against a piece of standard copier paper, like the way a pencil is used to write on paper. The abrasion bet…
Single-Material Graphene Thermocouples
Achim Harzheim, Fabian Könemann, Bernd Gotsmann +2
On-chip temperature sensing on a micro- to nanometer scale is becoming more desirable as the complexity of nanodevices and size requirements increase and with it the challenges in…
Trapping and electrical characterization of single core/shell iron-based nanoparticles in self-aligned nanogaps
Jacqueline Labra-Muñoz, Zorica Konstantinovic, Lluis Balcells +3
We report on the fabrication and measurements of platinum-self-aligned nanogap devices containing cubed iron (core)/iron oxide (shell) nanoparticles (NPs) with two average differen…
Very large scale characterization of graphene mechanical devices using a colorimetry technique
Santiago Jose Cartamil-Bueno, Alba Centeno, Amaia Zurutuza +3
We use a scalable optical technique to characterize more than 21000 circular nanomechanical devices made out of suspended single- and double-layer graphene on cavities with differe…
Graphene mechanical pixels for Interferometric MOdulator Displays (GIMOD)
Santiago J. Cartamil-Bueno, Dejan Davidovikj, Alba Centeno +4
Graphene, the carbon monolayer and 2D allotrope of graphite, has the potential to impact technology with a wide range of applications such as optical modulators for high-speed comm…
Graphene gas pumps
Dejan Davidovikj, Damian Bouwmeester, Herre S. J. van der Zant +1
We report on the development of a pneumatically coupled graphene membrane system, comprising of two circular cavities connected by a narrow trench. Both cavities and the trench are…
Static capacitive pressure sensing using a single graphene drum
Dejan Davidovikj, Paul H. Scheepers, Herre S. J. van der Zant +1
To realize nanomechanical graphene-based pressure and gas sensors, it is beneficial to have a method to electrically readout the static displacement of a suspended graphene membran…
