Effects of alloying elements (Pt or Co) on nickel-based contact technology for GeSn layers
Andrea Quintero,Patrice Gergaud,Jean-Michel Hartmann,Vincent Reboud,Eric Cassan,Philippe Rodriguez +5 more
- 01 Jun 2019
TL;DR: In this paper, the impact of Pt or Co alloying on Ni-based metallization in order to efficiently contact GeSn layers was investigated, and solid-state reactions, surface morphology and electrical properties were studied, as a function of temperature annealing.

Method for manufacturing a substrate provided with two active areas with different semi-conductor materials
Jean-Michel Hartmann
- 25 Oct 2011
TL;DR: In this article, a substrate is etched to define active areas, each having the layers, and the latter layer of the former active area is eliminated, so as to obtain a main surface (A1) made of semiconductor material, where the latter active area has another main surface made of the latter material and comprises the former layer.

Single Mode Mid-infrared Waveguide for Evanescent Sensor Scheme in Liquids
Yu-Chi Chang,Vincent Paeder,Jean-Michel Hartmann,Philip Wägli,Alexandra Homsy,Lubos Hvozdara,Hans Peter Herzig +6 more
- 01 Jan 2011
TL;DR: In this article, a Si/Ge based, single mode, mid-infrared optical waveguide is used as an evanescent sensor in liquid matrix for cocaine detection in human saliva at 5.81 microns.
