High Tech Career Competition 2021

PHOTONIS is a leading multinational high-technology group, manufacturing electro-optic components used in the detection of ions, electrons and photons. We innovate and engineer quality components for integration into a variety of applications such as night vision optics, digital cameras, mass spectrometry, physics research, space exploration and many others.

Description

Alkaliantimonide photocathodes are semi-conductive layers used to transfer light into electrons. Ideally 100% of incoming photons transfer their energy into electrons. You will work on the surface modification and characterization of the substrate onto which the photocathode material is growing. 

Goal

Improvement of surface preparation techniques to increase the performance of multi-alkali photocathodes.

Tasks

  • Survey of our current coating methods and technological weaknesses.
  • Proposal of new methods and trials
  • Characterization made using SEM/EDX, Filmetrics, DekTak microscopes etc.
  • Pilot tests with new ideas.

Key words

  • Material science
  • Wet and dry chemical modification of surfaces
  • Characterization of surfaces

We offer

A full time internship in a booming high-tech company for a period of 6 months

Requirements

  • Technical background on Academic level
  • Chemistry / Physics / Mechanical Engineering
