In this review, we report on fabrication paths, challenges, and emerging solutions to integrate group-IV epitaxial quantum dots (QDs) as active light emitters into the existing …
We present evidence of homogenization of atomic diffusion properties caused by C and N interstitials in an equiatomic single-phase high entropy alloy (FeMnNiCoCr). This …

We have applied positron annihilation spectroscopy to study the vacancy-type defects in β- Ga 2 O 3 single crystals. The three different types of crystals were prepared by Czochralski …
Depth-profiled pulsed low-energy positron annihilation lifetime spectroscopy and Doppler broadening spectroscopy were combined to identify vacancy-related complexes and probe …
The quest for metal-oxide-semiconductor field-effect transistors (MOSFETs) with higher carrier mobility has triggered great interest in germanium-based MOSFETs. Still, the …
Understanding the mechanisms of damage formation in materials irradiated with energetic ions is essential for the field of ion-beam materials modification and engineering. Utilizing …
We have applied positron annihilation spectroscopy to study native point defects in Te- doped n-type and nominally undoped p-type GaSb single crystals. The results show that the …
