Direct Observation of Ultrafast Exciton Formation in a Monolayer of WSe.

Nano letters

Steinleitner P, Merkl P, Nagler P, Mornhinweg J, Schüller C, Korn T, Chernikov A, Huber R.
PMID: 28182430
Nano Lett. 2017 Mar 08;17(3):1455-1460. doi: 10.1021/acs.nanolett.6b04422. Epub 2017 Feb 13.

Many of the fundamental optical and electronic properties of atomically thin transition metal dichalcogenides are dominated by strong Coulomb interactions between electrons and holes, forming tightly bound atom-like states called excitons. Here, we directly trace the ultrafast formation of...

Ultrabroadband etalon-free detection of infrared transients by van-der-Waals contacted sub-10-µm GaSe detectors.

Optics express

Opt Express. 2018 Jul 23;26(15):19059-19066. doi: 10.1364/OE.26.019059.

We demonstrate ultrabroadband electro-optic detection of multi-THz transients using mechanically exfoliated flakes of gallium selenide of a thickness of less than 10 µm, contacted to a diamond substrate by van-der-Waals bonding. While the low crystal thickness allows for extremely...

IL-7 and IL-8 inhibit gamete interaction in the zona-free hamster egg sperm penetration assay.

Mediators of inflammation

Lambert H, Collazo I, Steinleitner A.
PMID: 18475444
Mediators Inflamm. 1992;1(1):67-9. doi: 10.1155/S0962935192000139.

Current thought in reproductive endocrinology suggests hat endometriosis-associated subfertility may be the result of an adverse influence of activated immunocompetent cells on fertilization and embryo development. Inflammatory ediators such as interleukin-1 and tumour necrosis actor have been implicated in...

Excitonic Valley Effects in Monolayer WS.

Nano letters

Plechinger G, Nagler P, Arora A, Granados Del Águila A, Ballottin MV, Frank T, Steinleitner P, Gmitra M, Fabian J, Christianen PC, Bratschitsch R, Schüller C, Korn T.
PMID: 27960453
Nano Lett. 2016 Dec 14;16(12):7899-7904. doi: 10.1021/acs.nanolett.6b04171. Epub 2016 Nov 29.

Transition-metal dichalcogenides can be easily produced as atomically thin sheets, exhibiting the possibility to optically polarize and read out the valley pseudospin of extremely stable excitonic quasiparticles present in these 2D semiconductors. Here, we investigate a monolayer of tungsten...

Nat Mater. 2015 Sep;14(9):889-93. doi: 10.1038/nmat4356. Epub 2015 Jul 13.

Atomically thin two-dimensional crystals have revolutionized materials science. In particular, monolayer transition metal dichalcogenides promise novel optoelectronic applications, owing to their direct energy gaps in the optical range. Their electronic and optical properties are dominated by Coulomb-bound electron-hole pairs...
