Direct laser writing of high aspect ratio nanochannels for nanofluidics
Stoffel D. Janssens, Meissha Ayu Ardini, David Vázquez-Cortés +2
Nanochannels with high width-to-height aspect ratios are desirable for many applications, particularly those requiring optical access, but remain challenging to fabricate. In this…
Probing growth precursor diffusion lengths by inter-surface diffusion
Stoffel D. Janssens, Francisco S. Forte Neto, David Vázquez-Cortés +2
Understanding and optimizing thin-film synthesis requires measuring the diffusion length of adsorbed growth precursors. Despite technological advances, in-situ measurements o…
Early stages of polycrystalline diamond deposition: Laser reflectance at substrates with growing nanodiamonds
David Vázquez-Cortés, Stoffel D. Janssens, Burhannudin Sutisna +1
The chemical vapor deposition of polycrystalline diamond (PCD) films is typically done on substrates seeded with diamond nanoparticles. Specular laser reflectance and a continuous…
Formation and morphology of closed and porous films grown from grains seeded on substrates: Two-dimensional simulations
Stoffel D. Janssens, David Vázquez-Cortés, Eliot Fried
Two-dimensional simulations are used to explore topological transitions that occur during the formation of films grown from grains that are seeded on substrates. This is done for a…
Boundary Curvature Effect on the Wrinkling of Thin Suspended Films
Stoffel D. Janssens, Burhannudin Sutisna, Alessandro Giussani +2
In this letter, we demonstrate a relation between the boundary curvature and the wrinkle wavelength of a thin suspended film under boundary confinement. Experiments are don…
Nanocrystalline diamond-glass platform for the development of three-dimensional micro- and nanodevices
Stoffel D. Janssens, David Vázquez-Cortés, Alessandro Giussani +2
Low-cost and robust platforms are key for the development of next-generation 3D micro- and nanodevices. To fabricate such platforms, nanocrystalline diamond (NCD) is a highly appea…
Behavior of self-propelled acetone droplets in a Leidenfrost state on liquid substrates
Stoffel D. Janssens, Satoshi Koizumi, Eliot Fried
It is demonstrated that non-coalescent droplets of acetone can be formed on liquid substrates. The fluid flows around and in an acetone droplet hovering on water are recorded to sh…
Effect of a surface tension imbalance on a partly submerged cylinder
Stoffel D. Janssens, Vikash Chaurasia, Eliot Fried
We perform a static analysis of a circular cylinder that forms a barrier between surfactant-laden and surfactant-free portions of a liquidgas interface. In addition to determini…
Pick-up and drop transfer of diamond nanosheets
V. Seshan, J. O. Island, R. van Leeuwen +9
Nanocrystalline diamond (NCD) is a promising material for electronic and mechanical micro- and nanodevices. Here we introduce a versatile pick-up and drop technique that makes it p…
Current-induced nanogap formation and graphitization in boron-doped diamond films
V. Seshan, C. R. Arroyo, A. Castellanos-Gomez +9
A high-current annealing technique is used to fabricate nanogaps and hybrid diamond/graphite structures in boron-doped nanocrystalline diamond films. Nanometer-sized gaps down to 1…
