Journal ArticleDOI
Low Temperature Surface Cleaning of Silicon and Its Application to Silicon MBE
TL;DR: In this article, a low temperature thermal cleaning method for Si molecular beam epitaxy (MBE) is proposed, which consists of wet chemical treatment to eliminate carbon contaminants on Si substrates, thin oxide film formation to protect the clean Si surface from contamination during processing before MBE growth, and desorption of the thin oxide films under UHV.
Journal ArticleDOI
Surface segregation of In atoms during molecular beam epitaxy and its influence on the energy levels in InGaAs/GaAs quantum wells
TL;DR: In this article, surface segregation of In atoms during molecular beam epitaxy (MBE) and its influence on the energy levels in InGaAs/GaAs quantum wells were systematically studied using secondary ion mass spectroscopy (SIMS) and photoluminescence (PL).
Journal ArticleDOI
Island formation during growth of Ge on Si(100): A study using photoluminescence spectroscopy
TL;DR: In this article, a photoluminescence (PL) study on the growth mode changeover during growth of Ge on Si(100) substrates was carried out and the onset of the 3D island formation was determined to be 3.7 monolayers (ML).
Journal ArticleDOI

Seiro Miyoshi,Kentaro Onabe,N. Ohkouchi,Hiroyuki Yaguchi,Susumu Fukatsu,Yasuhiro Shiraki,Ryoichi Ito +6 more
TL;DR: In this paper, cubic GaN epitaxial films were successfully grown on (100) GaAs sunstrates by metalorganic vapor phase epitaxy (MOVPE) using 1,1-dimethylhydrazine (DMHy) as the nitrogen source material.
Journal ArticleDOI
Control of Ge dots in dimension and position by selective epitaxial growth and their optical properties
TL;DR: In this paper, the Stranski-Krastanov growth method was combined with selective epitaxial growth technique in windows surrounded by SiO2 films on Si substrates, and a single dot was grown in a window with the size of less than 300 nm.
