(author), Sudhölter, E.J.R. (author), De Smet, L.C.P.M. (author), Van der Zant, H.S.J. (author), Dulic, D. (author)A high-current annealing technique is used to fabricate nanogaps and hybrid diamond/graphite structures in boron-doped nanocrystalline diamond films. Nanometer-sized gaps down to ?1?nm are produced using a feedback-controlled current annealing procedure. The nanogaps are characterized using scanning electron microscopy and electronic transport...journal article 2012

Heremans, F.J. (author), Fuchs, G.D. (author), Wang, C.F. (author), Hanson, R. (author), Awschalom, D.D. (author)We report time-dependent photocurrent and transport measurements of sub-bandgap photoexcited carriers in nitrogen-rich (type Ib), single-crystal diamond. Transient carrier dynamics are characteristic of trapping conduction with long charge storage lifetimes of ? 3?hours. By measuring the photoexcited Hall effect, we confirm that the charge...journal article 2009
