Enhanced van der Waals epitaxy via electron transfer-enabled interfacial dative bond formation
Weiyu Xie, Toh-Ming Lu, Gwo-Ching Wang +2
Enhanced van der Waals (vdW) epitaxy of semiconductors on layered vdW substrate is identified as the formation of dative bonds. For example, despite that NbSe2 is a vdW layered mat…
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…
