Due to the spin-orbital coupling in a semiconductor quantum dot, a freelyprecessing electron spin produces a time-dependent charge density. This createsa sizeable electric field outside the dot, leading to promising applications inspintronics. The spin-electric coupling can be employed for non-invasive singlespin detection by electrical methods. We also consider a spin relaxationmechanism due to long-range coupling to electrons in gates and elsewhere in thesystem, and find a contribution comparable to, and in some cases dominant overpreviously discussed mechanisms.Comment: 4 pages, 2 figure
