Radiation Hardness Study of the ePix100 Sensor and ASIC under Direct Illumination at the European XFEL
I. Klačková, K. Ahmed, G. Blaj +10
The ePix detector family provides multiple variants of hybrid pixel detectors to support a wide range of applications at free electron laser facilities. We present the results of a…
Solid-state neutron detectors based on thickness scalable hexagonal boron nitride
Kawser Ahmed, Rajendra Dahal, Adam Weltz +3
This paper reports on the device processing and characterization of hexagonal boron nitride (hBN) based solid-state thermal neutron detectors, where hBN thickness varied from 2.5 t…
Metalorganic chemical vapor deposition of hexagonal boron nitride on (001) sapphire substrates for thermal neutron detector applications
Kawser Ahmed, Rajendra Dahal, Adam Weltz +3
This paper reports on the growth and characterization of hexagonal boron nitride (hBN) and its use for solid-state thermal neutron detection. The hBN epilayers were grown by metalo…
Effects of sapphire nitridation and growth temperature on the epitaxial growth of hexagonal boron nitride on sapphire
Kawser Ahmed, Rajendra Dahal, Adam Weltz +3
This paper reports on the epitaxial growth of hexagonal boron nitride (hBN) films on sapphire substrates in a cold wall chemical vapor deposition (CVD) system where different sapph…
