Cross-Section AFM and EFM Examination of Thin-Film Solar Cells

, 2020
We demonstrated the feasibility of analyzing cross sections of thin-film CdTe/CdS and CIGS/CdS solar cells using atomic force microscopy (AFM). The AFM images were compared with images obtained with the scanning electron microscopy (SEM), and the ...

A new electric field mill array with each of the mill’s rotor controlled precisely by a GPS module: Equipment and initial results

Earth and Planetary Physics
We have newly designed an electrostatic sensor, called an electric field mill (EFM), to simplify the estimation of the charge position and charge amount transferred by lightning discharges.

EFM-DBSCAN: Ein baumbasierter Clusteringalgorithmus unter Ausnutzung erweiterter Leader-Umgebungen

, 2017
DBSCAN ist ein dichte-basierter Clusteringalgorithmus, der beliebig geformte Cluster erkennt und sie von Rauschen trennt. Aufgrund der Laufzeit von O(n^2) ist seine Anwendung jedoch auf kleine Datenkollektionen beschränkt.
