In-situ wavelength calibration without a calibration target: use of Fraunhofer lines after landing on planetary surface
Shoki Mori, Ute Boettger, Maximilian Buder +14
Accurate wavelength calibration is critical for qualitative and quantitative spectroscopic measurements. Many spectrometers for planetary exploration are equipped with onboard cali…
Thermal activation of valley-orbit states of neutral magnesium in silicon
Rohan Abraham, Valentina Shuman, Leonid Portsel +7
Interstitial magnesium acts as a moderately deep double donor in silicon, and is relatively easily introduced by diffusion. Unlike the case of the chalcogen double donors, the bind…
Resolving isotope splitting of boron-related intracenter transitions in diamond by infrared absorption spectroscopy
Dmitrii Prikhodko, Sergey Pavlov, Sergey Tarelkin +7
Isotopic enrichment offers cutting-edge properties of materials opening exciting research and development opportunities. In semiconductors, reached progress of ultimate control in…
A Mg-pair isoelectronic bound exciton identified by its isotopic fingerprint in Si
Rohan Abraham, Adam DeAbreu, Kevin Morse +9
We use the greatly improved optical linewidths provided by highly enriched Si to study a photoluminescence line near 1017 meV previously observed in the luminescence spectru…
Further investigations of the deep double donor magnesium in silicon
Rohan Abraham, Adam DeAbreu, Kevin Morse +9
The deep double donor levels of substitutional chalcogen impurities in silicon have unique optical properties which may enable a spin/photonic quantum technology. The interstitial…
Symbiotic Optimization of the Nanolithography and RF-Plasma Etching for Fabricating High-Quality Light-Sensitive Superconductors on the 50 nm Scale
H. Bartolf, K. Inderbitzin, L. B. Gómez +6
We present results of a fabrication-process development for the lithographic pattern transfer into the sub-100nm range by combining electron-beam lithography and reactive dry etchi…
