By varying the energy and dose of tightly-focused electron beams, researchers have demonstrated the ability to both etch away and deposit high-resolution nanoscale patterns on two-dimensional layers of graphene oxide.

Scientists at the U.S. Department of Energy’s Ames Laboratory have discovered that applying vibrational motion in a periodic manner may be the key to preventing dissipations of the desired electron states that would make advanced quantum computing and spintronics possible (npj Quantum Materials, “Light Control of Surface-Bulk Coupling by Terahertz Vibrational Coherence in a Topological Insulator”).
