The 21st edition of the International Conference on "High Magnetic Fields in Semiconductor Physics” (HMF-21) will be held August 3-8, 2014 in Edgewater Beach and Golf Resort, Panama City Beach, Florida, USA. Our overall goal is to bring together leading experts, emerging scholars and young researchers, working in various areas of condensed matter physics, to establish a stimulating atmosphere of extensive discussions. The conference, with its estimated audience of 200+, offers various and flexible sponsorship and exhibitor options. Sponsoring the HMF-21 helps promote your company or laboratory, while helping to offset participation costs for junior scientists and students. By exhibiting at HMF-21, your company will also have the opportunity to engage in direct discussions with physicists from major research laboratories and universities. The exhibitor area will be open Monday through Wednesday, August 4-6. It will be conveniently located next to our Oral and Poster Sessions Hall to allow for ample traffic flow.
