Yes, plenty! Warren Ellis has some great stuff, particularly Transmetropolitan, Global Frequency, and now Trees¹. The Private Eye is an independent series, also ongoing, about a near future where privacy is much more important to society. The Fuse is a policial where all the events happen in a "floating city", orbiting around the Earth. Planetoid and Who is Jake Ellis are both good short series (4 and 5 issues, respectively), though the latter may not fit as sci-fi necessarily. Last but not least, there's Prophet, though that's a more fantasy mixed work.<p>I recommend looking into publishers such as Image Comics (lots of good creator-owned series with cheap DRM-free releases) and Vertigo, a DC imprint dedicated to different kinds of works, which includes both Transmet and V for Vendetta.<p>¹ My favorite work by him is actually Fell, but there's nothing futuristic or techy about it.
