July 2, 2015 4:30-6:00 BSB-108 Engineering Physics Student Colloquium Series Benchtop fabrication of multi-scale microelectromagnets for capturing magnetic particles Amin Hosseini Micro-electromagnets hold great promise for integration into portable and handheld labon-a- chip systems applicable to point-of-care disease management. Two major requirements must be satisﬁed in order for such devices to be applicable into practical, miniaturized, and portable biomedical instrumentation: low power operation and low-cost fabrication. Here, we use numerical modeling combined with a lithography-free fabrication process to create micro-electromagnets on a polymer substrate. Amorphous Semiconductors: importance, applications and bandgap formation Giacomo Bosco Amorphous materials have attracted some attention in the last few decades. First because their many industrial applications (going from solar cells, thin ﬁlm transistors, light sensors etc.) and, second, for the lack of understanding from many of its properties. In this short talk I will give a short overview of Amorphous Semiconductors importance showing some of its applications and give a special attention to its electronic properties in order to give a qualitative picture of bandgap formation.
