Investigation of the Annealing Behaviour of Implanted Nitrogen in n-type InP
نویسندگان
چکیده
Concentration profiles of nitrogen in vacuum-annealed n-type single crystal (100) InP implanted with 1x10 30-keV N ions cm have been studied by the secondary ion mass spectrometry (SIMS) and nuclear resonance broadening (NRB) techniques. Damage induced by the nitrogen implantation was studied by Rutherford backscattering spectrometry (RBS) and channeling. Annealing the InP samples led to loss and redistribution of nitrogen in the temperature range from 575 C to 675 C. At temperatures from 575 C to 600 C rapid migration of nitrogen towards the sample surface was observed. Based on isochronal annealing measurements two different recovery stages were observed. The recovery energies for nitrogen migration and recrystallization are 2.9 and 3.0 eV.

1 MeV Fe' was implanted into n-type InP and InGaAs layers at different substrate temperatures, -196'C, room temperature (RT), 100°C and 2OO0C to obtain highresistivity regions. The sheet resistivity of the InP and InGaAs epilayers grown on semiinsulating (SI) InP substrates was measured as a function of substrate temperature and post-implantation annealing temperature (100 SOO'C). For InP, a ma...

High-energy implantation of iron in n-type doped InP epilayers at different substrate temperatures: 77K, room temperature (RT), 1000C and 2000C was investigated to study the electrical isolation of n-type InP. Iron isolation implants were performed at 1MeV with a fluence of 5x1014 /cm2. This isolation scheme was chosen to place most of the iron atoms well inside the n-type doped layer. The shee...
