Lay Summary (French)

Lead
Four à chauffage laser pour la croissance de nouveaux matériaux
Lay summary

Ce projet a pour objectif la mise en place d’un four à zone flottante chauffé par Laser pour la croissance de monocristaux de qualité supérieure et d’une très large gamme en terme de composition chimique. Ces échantillons seront exploités pour des investigations scientifiques. La singularité du système au centre de ce projet réside dans l’utilisation de 5 diodes laser pour chauffer le four. Cette technique innovante permet d’obtenir un contrôle optimal de la zone fondue avec des caractéristiques bien plus précises que dans les fours à zone flottante utilisant des lampes halogènes. Le four sera utilisé pour la croissance d’un grand nombre d'échantillons qui seront utilisés par de nombreux groups de recherche de l’EPFL. Ces matériaux permettront aussi d’ouvrir de nouvelles collaborations avec toutes les institutions de recherche en Suisse.

Lay Summary (English)

Lead
Laser heated furnace for growing crystals of novel materials
Lay summary
This project will establish a Floating Zone Furnace for growth of highest quality single crystals of a vast range of materials to be exploited for scientific investigations. The uniqueness of the proposed instrument is that heating is achieved by 5 powerful laser diodes, which produces a much more accurate molten zone. The equipment will be used to grow samples for a wide range of scientific projects by several groups within EPFL and will be open to collaborations with all Swiss research institutions.

Abstract

We hereby request acquisition of a Floating Zone Furnace for growth of highest quality single crystals of a vast range of materials to be exploited for scientific investigations. The uniqueness of the proposed instrument is that heating is achieved by 5 powerful laser diodes, which produces a much more accurate molten zone. The equipment will be used to grow samples for a wide range of scientific projects by several groups within EPFL and will be open to collaborations with all Swiss research institutions.
