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.
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.
Dr. Thomas Stelzner studied chemistry at the University of Jena and received his PhD in glass chemistry in 1992. Afterwards he had a seven month stay at the New York State College of Ceramics supported by a grant of the DAAD. Between 1994 and 1998 we joined the Institute of Geosciences at the University of Jena, where he worked on meteorite research. From 1999-2000 he was the head of the analytical laboratory of a ceramic company in Hermsdorf / Thuringia. Since 2001 he is a research staff member at the IPHT, where he initially worked in the fields of high-temperature superconducting films and wear resistant coatings. The present areas of research are focused on the fabrication and characterization of silicon nanostructures for photonic and electronic applications. He has more than 35 peer-reviewed publications.
Dr. rer. nat. MSc. BSc. Vladimir A. Sivakov studied chemistry at the University of Vilnius (Lithuania, MOCVD group prof. A. Abrutis) until 2000 and received the PhD in 2004 from the Universität des Saarlandes (Germany, group prof. Veith/prof. Mathur). From 2005-2008 he was a PostDoc in Prof. U. Gösele group at the Max-Planck-Institute of Microstructure Physics in Halle. Since 2008 he is a research staff member at the IPHT Jena. He has significant experience in the field of thin film technology, nanostructure synthesis and characterization as well as semiconductor technology. Other essentially basic research oriented projects were related to self assembled nanowire growth and characterization, nanopatterning using electron beam lithography and nanoimprint lithography for optoelectronic and photovoltaic applications. He has more than 30 peer-reviewed publications.
