Computational rule-based approach for corner correction of non-Manhattan geometries in mask aligner photolithography

Toralf Scharf, Wilfried Noell, Chen Yan, Raoul Kirner, Andreas Vetter

In proximity mask aligner photolithography, diffraction of light at the mask pattern is the predominant source for image shape distortions such as line end shortening and corner rounding. One established method to mitigate the impact of diffraction is opti ...

A plane linkage and its tessellation for deployable structure

Chen Yan, Huijuan Feng

Deployable structures are widely used in space applications such as solar arrays and antennas. Recently, inspired by origami, more deployable structures have been developed. This paper outlined a novel design scheme for deployable structures by taking a pl ...

MoS2/VO2 vdW heterojunction devices: Tunable rectifiers, photodiodes and field effect transistors

Olivier Martin, Mihai Adrian Ionescu, Arnaud Magrez, Andreas Schueler, Anna Krammer, Emanuele Andrea Casu, Chen Yan, Nicolò Oliva

In this work we report a new class of ultra-thin film devices based on n-n van der Waals (vdW) heteroj unctions of MoS2 and VO2, which show remarkable tunable characteristics. The favorable band alignment combined with the sharp and clean vdW interface det ...

Van der Waals MoS2/VO2 heterostructure junction with tunable rectifier behavior and efficient photoresponse

Mihai Adrian Ionescu, Olivier Martin, Arnaud Magrez, Andreas Schueler, Igor Stolichnov, Anna Krammer, Teodor Rosca, Emanuele Andrea Casu, Nicolò Oliva, Chen Yan

Junctions between n-type semiconductors of different electron affinity show rectification if the junction is abrupt enough. With the advent of 2D materials, we are able to realize thin van der Waals (vdW) heterostructures based on a large diversity of mate ...

Revealing a Mode Interplay That Controls Second-Harmonic Radiation in Gold Nanoantennas

Olivier Martin, Jérémy Butet, Gabriel David Bernasconi, Chen Yan

In this work, we investigate the generation of second- harmonic light by gold nanorods and demonstrate that the collected nonlinear intensity depends upon a phase interplay between di ff erent modes available in the nanostructure. By recording the backward ...

Full Color Generation Using Silver Tandem Nanodisks

Olivier Martin, Christian Santschi, Chen Yan, Xiaolong Wang, Jingwen Zhang, Hua Zhao

Plasmonic effects associated with metallic nanostructures have been widely studied for color generation. It became apparent that highly saturated and bright colors are hard to obtain, and very small nanostructures need to be fabricated. To address this iss ...
