Maskless selective growth of Mg-doped GaAs films was performed by using a low-energy (30-200 eV) Mg-Ga focused ion beam (FIB) under the ambient of As 4 molecular beam. Under suitable As 4 pressure, all samples showed p-type and the carrier concentrat

Maskless selective growth of Be-doped GaAs films was performed by using a low-energy (30–200 eV) Be–Ga focused ion beam (FIB) with the irradiation of As4 molecular beam simultaneously. As a result, the selective p-type films of GaAs were grown su

We introduced a new growth and doping method and demonstrated in-situ maskless selective doped-GaAs films by using a Ga–Sn low energy focused ion beam. This in-situ growth-doping method is thought to be essential in the maskless selective device fa

For the first time, we attempted to grow maskless selective epitaxial films of InGaN and obtained cubic InGaN on GaAs (1 0 0) and hexagonal InGaN on GaAs (1 1 1) A and (1 1 1) B substrates by using an InGa low energy focused ion beam and dimethylhydr

In this study, we have demonstrated maskless selective epitaxy (MLSE) of In x Ga 1− x As on GaAs substrate using a low-energy In 0.15 Ga 0.85 -FIB and an As 4 molecular beam. We used an In 0.15 Ga 0.85 liquid alloy ion source (LAIS) as a source of

Tertiarybutylhydrazine (TBHy) is one of the alternative nitrogen sources to ammonia. We investigated pyrolysis of TBHy using quadrupole mass spectrometer and grew GaN films on (0 0 0 1) sapphire substrates by low-pressure metal-organic vapor-phase ep

In-situ maskless selective epitaxy of GaAs was performed with a low-energy Ga focused ion beam (FIB) and an As 4 molecular beam. The low-energy Ga FIB and the As 4 were supplied simultaneously on GaAs(100) substrates. The incident energy (E i ) of th
