چکیده

Glassy ferromagnetism is observed in diluted magnetic semiconductor Al-doped 4H-SiC. We propose a possible explanation for the origin of ferromagnetism order that is the coeffect of sp(2)/sp(3) configuration along with the structural defects. This result unambiguously demonstrates the existence of intrinsic ferromagnetism order in nonmagnetic sp systems.

The Role of Ga(Gallium)-flux and AlN(Aluminum Nitride) as the Interface Materials, between (Ga-face)GaN and (Siface)4H-SiC, through Molecular Dynamics Simulation

We report here, the results of molecular dynamics simulation of p-doped (Ga-face)GaN over n-doped (Siface)(0001)4H-SiC hetero-epitaxial material system with one-layer each of Ga-flux and (Al-face)AlN, as the interface materials, in the form of, the total Density of States (DOS). It is found that the total DOS at the Fermi-level for the heavily p-doped (Ga-face)GaN and ndoped (Si-face)4H-SiC het...

Characteristics of the intrinsic defects in unintentionally doped 4H-SiC after thermal annealing

Thermal annealing effects on the characteristics of intrinsic defects in unintentionally doped 4H–SiC were investigated. The 4H–SiC samples were prepared by Low-Pressure Chemical Vapor Deposition (LPCVD) technique. Results show that there is only one Electron Spin Resonance (ESR) peak and a broad, from green to yellow, photoluminescence (PL) band were detected. These results are attributed to t...

Solubility limit and precipitate formation in Al-doped 4H-SiC epitaxial material

Heavily Al-doped 4H–SiC structures have been prepared by vapor phase epitaxy. Subsequent anneals have been carried out in an Ar atmosphere in a rf-heated furnace between 1500 °C and 2000 °C for 0.5 to 3 h. Secondary ion mass spectrometry has been utilized to obtain Al concentration versus depth as well as lateral distributions ~ion images!. Transmission electron microscopy ~TEM! has been employ...

Luminescence Properties of Oxyfluoride Glass and Glass Ceramic Doped with Y3 + Ions

 Oxyfluoride glass ceramics containing CaF2nano-crystals doped with Y3+ ions were prepared by one-step crystallization of SiO2- Al2O3- CaO- CaF2 glasses at different temperatures. X- ray diffraction (XRD) results have revealed that CaF2 was the only precipitated crystalline phase in glass ceramic samples. According to the XRD results, a glass ceramic was selected as the best sample in order to ...

4 H – SiC Metal – Semiconductor – Metal Ultraviolet Photodetectors in Operation of 450 ◦ C

This work demonstrates the high-temperature operation of metal–semiconductor–metal (MSM) photodetectors (PDs) up to 450 ◦C using lightly Al-doped epitaxial 4H–SiC thin films. The responsivity of the PDs under 325-nm illumination is 0.0305 A/W at 20-V bias at room temperature. The photocurrentto-dark-current ratio of the SiC MSM PDs is as high as 1.3 × 10 at 25 ◦C and is 0.62 at 450 ◦C. The rise...
