Fundamental limit of quantum device simulations
by Joachim Piprek (Wed, 08 Nov 2017)

This pictures provides an atomistic view of an InGaN/GaN quantum well [1]. Inside this quantum well (QW), 17% of the Gallium atoms are replaced by Indium atoms which are here randomly distributed (red dots). Such QWs are employed in many modern light-emitting devices, from full-color displays to LED lamps. The emission wavelength is controlled by […]


A handbook by and for the NUSOD community
by Joachim Piprek (Thu, 26 Oct 2017)

Our NUSOD handbook was finally published this month, comprising 1682 pages with 52 chapters written by more than 100 experts from all over the world. I think the handbook format is ideal for beginners but it is also useful for experienced researchers who would like to update and broaden their knowledge in this field. Mathematical […]


High-power GaN-based laser with tunnel junction
by Joachim Piprek (Thu, 14 Sep 2017)

Thus far, the highest output power measured on GaN-based lasers is about 7W, as shown in the picture. [1] In comparison, some GaAs-based lasers emit more than 30W in continuous-wave operation at room temperature. A key reason for this difference is the inherently large p-side electrical resistance of GaN-based laser diodes. It leads to strong […]


NUSOD 2017 with record attendance
by Joachim Piprek (Tue, 01 Aug 2017)

A record number of 128 papers was presented last week at the NUSOD 2017 conference,  stimulating many valuable discussions. Summaries of all presentations are now available online. Poster prizes were awarded to papers MP01, MP25, and MP28. The rump session focused on improved publication methods as recently announced on this blog. I would like to […]


NUSOD 2017 Preview Rump Session: Words cannot express…! Research results are more than just plain text.
by Thomas Koprucki (Sat, 22 Jul 2017)

Whenever you try to answer a research question by using numerical simulation, you start by developing a (or reusing an already developed) mathematical model. Thereafter, you are developing (or reusing already developed) software to perform your numerical simulation. This produces data that you are now analysing and visualising to interpret the discovered results. Finally, you might […]
