- Current-voltage spectroscopy of the subband structure of strongly pinched-off quantum point contacts
[作者:Song, J; Kawano, Y; Ishibashi, K; Mikalopas, J; Aizin, GR; Aoki, N; Reno, JL; Ochiai, Y; Bird, JP,期刊:Applied Physics Letters, 页码:233115-233115 , 文章类型: Article,,卷期:2009年95-23]
- We demonstrate current-voltage spectroscopy of the one-dimensional subband structure of pinched-off quantum point contacts (QPCs). This technique yields the full subband structure and effective barrier of the QPC, withou...
- Origin of inverse tunneling magnetoresistance in a symmetric junction revealed by delaminating the buried electronic interface
[作者:Yang, JJ; Xiang, H; Ji, CX; Stickle, WF; Stewart, DR; Ohlberg, DAA; Williams, RS; Chang, YA,期刊:Applied Physics Letters, 页码:233117-233117 , 文章类型: Article,,卷期:2009年95-23]
- Electrical properties of modern electronic devices are usually controlled by the physical and chemical structure of one or more buried material interfaces. Accessing these buried interfaces by energetic ion milling can d...
- Evolution of the InAs wetting layer on GaAs(001)-c(4x4) on the atomic scale
[作者:Grabowski, J; Prohl, C; Hopfner, B; Dahne, M; Eisele, H,期刊:Applied Physics Letters, 页码:233118-233118 , 文章类型: Article,,卷期:2009年95-23]
- Scanning tunneling microscopy was used to investigate the development of the InAs wetting layer on the GaAs(001)-c(4x4) surface. At low InAs coverages signatures of indium agglomerations form on the surface, before an ab...
- Synthesis, characterization, and magnetic properties of room-temperature nanofluid ferromagnetic graphite
[作者:Souza, NS; Sergeenkov, S; Speglich, C; Rivera, VAG; Cardoso, CA; Pardo, H; Mombru, AW; Rodrigues, AD; de Lima, OF; Araujo-Moreira, FM,期刊:Applied Physics Letters, 页码:233120-233120 , 文章类型: Article,,卷期:2009年95-23]
- We report the chemical synthesis route, structural characterization, and physical properties of nanofluid magnetic graphite (NFMG) obtained from the previously synthesized bulk organic magnetic graphite (MG) by stabilizi...
- Hot electron effect in nanoscopically thin photovoltaic junctions
[作者:Kempa, K; Naughton, MJ; Ren, ZF; Herczynski, A; Kirkpatrick, T; Rybczynski, J; Gao, Y,期刊:Applied Physics Letters, 页码:233121-233121 , 文章类型: Article,,卷期:2009年95-23]
- The open circuit voltage in ultrathin amorphous silicon solar cells is found to increase with light energy (frequency), due to extraction of hot electrons. The ultrathin nature of these junctions also leads to large inte...
- Detection of percolating paths in polyhedral segregated network composites using electrostatic force microscopy and conductive atomic force microscopy
[作者:Waddell, J; Ou, R; Capozzi, CJ; Gupta, S; Parker, CA; Gerhardt, RA; Seal, K; Kalinin, SV; Baddorf, AP,期刊:Applied Physics Letters, 页码:233122-233122 , 文章类型: Article,,卷期:2009年95-23]
- Composite specimens possessing polyhedral segregated network microstructures require a very small amount of nanosize filler, <1 vol %, to reach percolation because percolation occurs by accumulation of the fillers along ...
