After implanting carbon atoms(concentration:1.5e17cm-3) into the shallow surface of 4H-SiC epilayer and annealing, DLTS and TRPL was used for characterization. ![]() ![]() The carrier traps Z1/2 and EH6/7 can be created by displacement of carbon atoms caused by electron radiation. Reduction of traps and improvement of carrier lifetime in 4H-SiC epilayers by ion implantation “SiC Migration Enhanced Embedded Epitaxial (ME3) Growth Technology”,in, Journal Article “Structures, Electronic Properties, and Gas Permeability of 3D Pillared Silicon Carbide Nanostructures”,in, Journal Article And there is a triangle defect in the direction. High symmetry is shown parallel to this direction. The symmetry of the epitaxial layer perpendicular to the inclination direction is not high There is a smooth surface and an epitaxial layer with high symmetry. The SiC substrate is obliquely oriented to, and the groove is parallel to, which can be grown ![]() The growth habit of n-shaped Sic homogeneous epitaxy without doping was studied under the condition of C/Si=2-4。The experimental conditions are as follows: In this work, electrical characteristics, α-particle response, and pulse response speed of 4H-SiC PIN diode detectors were carefully investigated under MeV equivalent neutron irradiation fluence from \(5 × 10^\), no postimplantation annealing process.Ģ.Growth conditions: 1500 degrees Celsius, atmospheric pressure, chemical vapor deposition methodģ.Raw material: SiH4C3H8 mixed gas, the carrier of the carrier gas is H2, using horizontal water-cooled reactor. In order to meet the demand for higher precision measurements, the eliability of SiC detectors under harsh neutron irradiation nvironments must be characterized. Silicon carbide (SiC) detector shows sufficient merits for the pplication of radiation measurement in harsh neutron radiation fields due to the strong radiation tolerance, good environment adaptability, and excellent electrical properties.
