Strong-Field Photoemission Experiment using Diamond Field Emitter Arrays
V. Pavlenko, D. Kim, H. L. Andrews +2
In this paper, we present the results of experimental observation of strong-field photoemission from a diamond field-emitter array (DFEA) illuminated by a focused laser beam with 1…
Quantum efficiency enhancement of bialkali photocathodes by an atomically thin layer on substrates
Hisato Yamaguchi, Fangze Liu, Jeffrey DeFazio +15
We report quantum efficiency (QE) enhancements in accelerator technology relevant antimonide photocathodes (K2CsSb) by interfacing them with atomically thin two-dimensional (2D) cr…
Free-standing bialkali photocathodes using atomically thin substrates
Hisato Yamaguchi, Fangze Liu, Jeffrey DeFazio +10
We report successful deposition of high quantum efficiency (QE) bialkali antimonide K2CsSb photocathodes on graphene films. The results pave a pathway towards an ultimate goal of e…
Active bialkali photocathodes on free-standing graphene substrates
Hisato Yamaguchi, Fangze Liu, Jeffrey DeFazio +10
The hexagonal structure of graphene gives rise to the property of gas impermeability, motivating its investigation for a new application: protection of semiconductor photocathodes…
Collective responses of Bi-2212 stacked junction to 100 GHz microwave radiation under magnetic field oriented along the c-axis
V. N. Pavlenko, Yu. I. Latyshev, J. Chen +4
We studied a response of Bi-2212 mesa type structures to 100 GHz microwave radiation. We found that applying magnetic field of about 0.1 T across the layers enables to observe coll…
Josephson vortex lattice melting in Bi-2212 probed by commensurate oscillations of Josephson flux-flow
Yu. I. Latyshev, V. N. Pavlenko, A. P. Orlov +1
We studied the commensurate semi-fluxon oscillations of Josephson flux-flow (JFF) in a Bi-2212 stacked structures near as a probe of melting of Josephson vortex lattice (JVL)…
Coherent Tunneling between Elementary Conducting Layers in the NbSe Charge-Density-Wave Conductor
Yu. I. Latyshev, A. A. Sinchenko, L. N. Bulaevskii +2
Characteristic features of transverse transport along the axis in the NbSe charge-density-wave conductor are studied. At low temperatures, the - characteristics of…
Novel features of Josephson flux-flow in Bi-2212: contribution of in-plane dissipation, coherent response to mm-wave radiation, size effect
Yu. I. Latyshev, A. E. Koshelev, V. N. Pavlenko +3
We studied Josephson flux-flow (JFF) in Bi-2212 stacks fabricated from single crystal whiskers by focused ion beam technique. For long junctions with the in-plane sizes 30 x 2 (mu)…
Interlayer Tunneling of Quasiparticles and Cooper Pairs in Bi-2212 Single Crystal Whiskers
Yu. I. Latyshev, V. N. Pavlenko, S. -J. Kim +6
The interlayer tunneling has been studied on high quality Bi-2212 stacks of micron to the submicron lateral size. We found that low temperature and low voltage tunneling I-V charac…
