BIB Detector for astrophysics applications: Principle of operation, technology and first experimental results

Abstract
This paper is a presentation of the activity that has been performed in the domain of Blocked Impurity Band detector, from the operating principle to the characterization.
This study has been performed commonly with IMEC in Belgium, MPIA Heidelberg and Thales Alenia Space in Cannes.
The presentation deals with:

• A brief description of the context and the organization of the study.
• A description of the BIB detector operating principle.
• A short presentation of the technological steps for the detector fabrication.
• The main outcomes of the experimentation at diode level and at array level.
