    Institute of Photonic Technology (IPHT) located in Jena, Germany, is a non-profit R&D organization of the state of Thuringia. 200 employees are working primarily in the fields of optics, material science, and light-matter interaction. The Photonic Silicon Division has a long standing experience in laser enhanced deposition of semiconductors on low temperature substrates using different deposition technologies and applying various laser systems ranging from cw to short pulse lasers to crystallize amorphous silicon layers on glass particularly for thin film solar cells. Moreover, the division is concerned with nanostructuring of silicon and bottom-up vapor phase growth of nanowires for novel electronic, photonic and sensor devices.


    Key personal:

    Priv. Doz. Dr. Silke Christiansen since recently group leader and research staff member at the IPHT, has significant experience in the field of thin film epitaxy, nano-structure synthesis and characterization as well as silicon technology. From 2002-2007 she jointly managed a group at the Max-Planck-Institute of Microstructure Physics and the Martin-Luther University, Halle. During this time she acquired several publicly funded projects, partly in large consortia such as TESIN with AMD, Infineon, Siltronic, Aixtron, IMEC, FZ Jülich, which was concerned with the realization of strained silicon-on-insulator for future nanoelectronics. Other essentially basic research oriented projects were related to self-assembled nanowire growth and characterization, nano-patterning using electron beam lithography and nano-imprint ithography for optoelectronic and photovoltaic applications. Between 2000 and 2002 she held a Feodor- Lynen grant form the Alexander von Humboldt foundation to work at the T.J. Watson Research Cente in Yorktown Heights, NY, USA in the Silicon Technology department on strained silicon for future nanoelectronics. During this time she submitted 5 patent applications, 4 of which are already granted. In 2001 she obtained her habilitation from the University of Erlangen-Nürnberg in the materials science department. In 1998 she obtained her PhD in materials science from the same university. In 1997 she obtained a grant from the Bavarian ministry of science to spend a research semester at the Columbia University, New York, working on laser crystallization of crystalline silicon films on glass and polymer substrates for thin film transistor and photovoltaic applications. She has more than 150 peer-reviewed publications.

    Priv. Doz. Dr. Fritz Falk heads the Photonic Silicon Department at the IPHT. He earned his PhD form the University of Stuttgart as a physicist in the field of continuum mechanics of defects in solids. 1977 he joined the theoretical physics group at the University of Paderborn to investigate the thermodynamics of solid-state phase transitions and obtained his habilitation in the physics department. After a stay at Oklahoma State University (USA) he 1988 joined the Applied Laser Department of Battelle Institute, Frankfurt, a privately owned R&D facility, where he was responsible for acquiring and heading industrial and federal projects. Particularly he headed an experiment during the space lab mission D2. Since 1993  he is division manager at the IPHT where he leads the photonic silicon group concerned with material modification by laser irradiation particularly for thin film solar cells and silicon nanostructures for photonic applications. He teaches applied theoretical solid state physics at the University of Jena. He has more than 100 peer reviewed publications.

    Dr. Michael Becker is research staff member in the group of Dr. S. Christiansen at the IPHT. His experiences lie in the fields of Raman spectroscopy, semiconductor physics, solar cell materials, FEMsimulations and TEM-analysis. In 2006 he obtained his PhD in materials science from the University of Erlangen-Nürnberg. In 2006/2007 he worked as a Post Doc at the Martin-Luther University of Halle Wittenberg. During his PhD-and Post Doc- activities he submitted 2 patent applications and published several articles dealing with Raman spectroscopy.

    Role in the project:

    IPHT will act as the project coordinator (WP12). In this task it will be supported by ALMA (Cr9). IPHT will be responsible for WP1 (Diode laser crystallized multi-crystalline seed layer on glass. It will work on WP2 to perform experiments on epitaxial SPE of amorphous silicon layers on the seed layer, on WPs3 and 4 to analyze internal stresses by EBSD and Raman spectroscopy, on WP5 delivering input to Cr3 concerning parameters needed for the development of the diode laser with line focus, and on WP6 delivering numerical simulations of the SPE process.

    Previous European funded projects:

    Subcontractor in the project ATHLET (2006-2009); subcontractor in the Medea+ project Silonis (2006-2008); Subcontractor in the project SINANO (2005-2008).
