A strong research activity has been focused on the chemistry of the material in order to establish the most important parameters which could further improve η and to collect photons from a broad energy window. The major trend in this field is in photovoltaic device engineering although the fundamental aspects of the material are not yet fully understood.</span></p><p style="color: #000000; font-family: 'times new roman', 'new york', times, serif; font-size: 12pt; margin: 15px; text-align: justify;"><span style="font-family: arial, helvetica, sans-serif;">In my laboratory, we have devoted considerable efforts to the growth of high-quality single crystals at different length scales, ranging from large bulk crystals (up to 10 cm<sup>3</sup>) through nanowires down to quantum dots of tens of nanometers of linear dimensions. The structural tunability of the material allows the study of a broad range of physical phenomena including electrical and thermal transport, magnetism, optical properties, band structure by photoemission etc. In this presentation, a selected set of measurements will be reported together with some device applications.</span></p><p style="color: #000000; font-family: 'times new roman', 'new york', times, serif; font-size: 12pt; margin: 15px; text-align: justify;"><span style="font-family: arial, helvetica, sans-serif;">Acknowledgement: The work has been performed in collaboration with Endre Horvath, Massimo Spina, Balint Nafradi, Peter Szirmai, Alla Araktcheva, Andrea Pisoni, Jacim Jacimovic, Andrzej Sienkiewicz, Claudio Grimaldi, Hugo Dil, Henrik Ronnow and many others.</span></p><p style="color: #000000; font-family: 'times new roman', 'new york', times, serif; font-size: 12pt; margin: 15px; text-align: justify;"><span style="font-family: arial, helvetica, sans-serif;"></span><br></p></div><div style="color: #000000; font-family: arial, helvetica, sans-serif; font-size: 12pt; text-align: left;"><b><span lang="EN-GB" style="font-size: 12pt; font-family: 'Century Gothic',sans-serif;"><b><span lang="EN-GB" style="font-size: 11pt; font-family: 'Century Gothic',sans-serif;"> </span></b></span></b><b><span lang="EN-GB" style="font-size: 12pt; font-family: 'Century Gothic',sans-serif;"><b><span lang="EN-GB" style="font-size: 11pt; font-family: 'Century Gothic',sans-serif;">Voditelji seminara IF-a: <a href="mailto:hrvoje@ifs.hr" target="_blank">Hrvoje Skenderović</a> i <a href="mailto:damirs@ifs.hr" target="_blank">Damir Starešinić</a></span></b></span></b></div></div></div></div></div></div><br></div></div></body></html>
