Thienothiophene Scaffolds as Building Blocks for (Opto)Electronics

open access: yesOrganics, 2022
Thieno[3,2-b]thiophene and isomeric thieno[2,3-b]thiophene represent fused, bicyclic and electron rich heterocycles. These small planar organic compounds belong to the remarkable family of annulated building blocks for various organic materials.

Wide-bandwidth mode-hop-free tuning of extended-cavity GaN diode lasers [PDF]

open access: yes, 2005
We present a new approach for extended-cavity diode-laser tuning to achieve wide mode-hop-free tuning ranges. By using a multiple piezoactuated grating mount, the cavity length and grating angle in the laser can be adjusted independently, allowing mode ...

A study of temperature-related non-linearity at the metal-silicon interface [PDF]

open access: yes, 2012
In this paper, we investigate the temperature dependencies of metal-semiconductor interfaces in an effort to better reproduce the current-voltage-temperature (IVT) characteristics of any Schottky diode, regardless of homogeneity.
