Probing Electronic States in Monolayer Semiconductors through Static and Transient Third-Harmonic Spectroscopy
Yadong Wang, Fadil Iyikanat, Habib Rostami +10
Electronic states and their dynamics are of critical importance for electronic and optoelectronic applications. Here, we probe various relevant electronic states in monolayer MoS2,…
Scaling of graphene field-effect transistors supported on hexagonal boron nitride: radio-frequency stability as a limiting factor
Pedro C. Feijoo, Francisco Pasadas, José M. Iglesias +7
The quality of graphene in nanodevices has increased hugely thanks to the use of hexagonal boron nitride as a supporting layer. This paper studies to which extent hBN together with…
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…
Broadband laser polarization control with aligned carbon nanotubes
He Yang, Bo Fua, Diao Lia +12
We introduce a simple approach to fabricate aligned carbon nanotube (ACNT) device for broadband polarization control in fiber laser systems. The ACNT device was fabricated by pulli…
Ultrafast pulse generation with black phosphorus
Diao Li, Henri Jussila, Lasse Karvonen +4
Black phosphorus has been recently rediscovered as a new and interesting two-dimensional material due to its unique electronic and optical properties. Here, we study the linear and…
Recent progress towards acoustically mediated carrier injection into individual nanostructures for single photon generation
Stefan Völk, Florian J. R. Schülein, Florian Knall +12
We report on recent progress towards single photon sources based on quantum dot and quantum post nanostructures which are manipulated using surface acoustic waves. For this concept…
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…
