Direct Observation of Acoustic Phonon Confinement in Free-Standing Semiconductor Nanowires
Fariborz Kargar, Bishwajit Debnath, Kakko Joona-Pekko +5
Similar to electron waves, the phonon states in semiconductors can undergo changes induced by external boundaries. Modification of acoustic phonon spectrum in structures with perio…
Ultra-strong nonlinear optical processes and trigonal warping in MoS layers
A. Säynätjoki, L. Karvonen, H. Rostami +11
We report ultra-strong high-order nonlinear multiphoton processes in monolayer MoS (1L-MoS): the third harmonic is thirty times stronger than the second harmonic, and the f…
A physics based model of gate tunable metal-graphene contact resistance benchmarked against experimental data
Ferney A. Chaves, David Jiménez, Abhay A. Sagade +4
The metal-graphene contact resistance is a technological bottleneck for the realization of viable graphene based electronics. We report a useful model to find the gate tunable comp…
Cascaded exciton emission of an individual strain-induced quantum dot
F. J. R. Schülein, A. Laucht, J. Riikonen +6
Single strain-induced quantum dots are isolated for optical experiments by selective removal of the inducing InP islands from the sample surface. Unpolarized emission of single, bi…
