With the 1988 discovery of giant magnetoresistance and its remarkable impact on hard-drive technology, the question has turned to whether it is possible to utilize the spin degree-of-freedom in semiconductor electronics for superior performance in some aspect (e.g. speed, power, function, etc.). Although there are several proposals, the answer is unclear and probably relies on developing a deeper understanding of the basic properties of electron spin in semiconductors. In this talk, I will break down a semiconductor spintronic device into four basic processes (spin-injection, spin-transport, spin-detection, and spin-manipulation) and discuss their properties within the context of our research on spin in graphene.  Through atomic-scale materials control and magnetotransport measurements, we are developing new insights in the recently emerging ferromagnet-graphene systems. Our success in the latter, as one of the first groups to achieve spin transport in graphene, is helping to establish a new field of research &mdash; graphene spintronics &mdash; which is attracting interest because it is the first semiconductor spintronic device to operate at room temperature and its unique band structure might generate unusual spin-dependent phenomena.<\/p>\n","protected":false},"author":1,"featured_media":0,"template":"","class_list":["post-3895","physics_colloquium","type-physics_colloquium","status-publish","hentry"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.hmc.edu\/physics\/wp-json\/wp\/v2\/physics_colloquium\/3895","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.hmc.edu\/physics\/wp-json\/wp\/v2\/physics_colloquium"}],"about":[{"href":"https:\/\/www.hmc.edu\/physics\/wp-json\/wp\/v2\/types\/physics_colloquium"}],"author":[{"embeddable":true,"href":"https:\/\/www.hmc.edu\/physics\/wp-json\/wp\/v2\/users\/1"}],"wp:attachment":[{"href":"https:\/\/www.hmc.edu\/physics\/wp-json\/wp\/v2\/media?parent=3895"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
