- Passivation of InP heterojunction bipolar transistors by strain controlled plasma assisted electron beam evaporated hafnium oxide - art. no. 014102
[作者:Driad, R; Sah, RE; Schmidt, R; Kirste, L,期刊:Applied Physics Letters, 页码:14102-14102 , 文章类型: Article,,卷期:2012年100-1]
- We present structural, stress, and electrical properties of plasma assisted e-beam evaporated hafnium dioxide (HfO2) layers on n-type InP substrates. These layers have subsequently been used for surface passivation of In...
- Motion detection of a micromechanical cantilever through magneto-piezovoltage in two-dimensional electron systems - art. no. 012106
[作者:Yamaguchi, H; Okamoto, H; Ishihara, S; Hirayama, Y,期刊:Applied Physics Letters, 页码:12106-12106 , 文章类型: Article,,卷期:2012年100-1]
- We study the strain-induced voltage generation, i.e., piezovoltage, in a two-dimensional electron system under a magnetic field at low temperature. We find its strong magnetic-field dependence, where the voltage increase...
- Mid-gap trap states in CdTe nanoparticle solar cells - art. no. 013508
[作者:Bezryadina, A; France, C; Graham, R; Yang, L; Carter, SA; Alers, GB,期刊:Applied Physics Letters, 页码:13508-13508 , 文章类型: Article,,卷期:2012年100-1]
- Thin film solar cells comprised of quantum-confined CdTe nanoparticles are shown to have a low intrinsic density of mid-gap trap states relative to their equivalent bulk film, indicating that the ligands are effective at...
- Nano-opto-mechanical actuator driven by gradient optical force - art. no. 013108
[作者:Cai, H; Xu, KJ; Liu, AQ; Fang, Q; Yu, MB; Lo, GQ; Kwong, DL,期刊:Applied Physics Letters, 页码:13108-13108 , 文章类型: Article,,卷期:2012年100-1]
- In this letter, a nanoscale opto-mechanical actuator driven by gradient optical force is designed and demonstrated. The nanoscale actuator can achieve a maximum displacement of 67 nm with a response time of 94.5 ns. The ...
- Optical feedback mechanisms in laser induced growth of carbon nanotube forests - art. no. 013112
[作者:Bock, MCD; Denk, R; Wirth, CT; Goldberg-Oppenheimer, P; Hofmann, S; Baumberg, JJ,期刊:Applied Physics Letters, 页码:13112-13112 , 文章类型: Article,,卷期:2012年100-1]
- We study optical feedback mechanisms occurring during growth of multi-walled carbon nanotube forests on transparent substrates. Growth is realised via laser-induced chemical vapour deposition using iron nanoparticle cata...
