/EC-SLI Collaboration
We have investigated the lattice location of implanted transition metal (TM) 56Mn, 59Fe and 65Ni ions in undoped single-crystalline cubic 3C–SiC by means of the emission channeling technique using radioactive isotopes produced at the CERN-ISOLDE facility. We find that in the room temperature as-implanted state, most Mn, Fe and Ni atoms occupy carbon-coordinated tetrahedral interstitial sites (TC). [...]

Influence of the doping on the lattice sites of Fe in Si
/ Silva, Daniel (Porto U.) ; Wahl, Ulrich (Lisbon, IST) ; Martins Correia, Joao (Lisbon, IST) ; Esteves De Araujo, Araujo Joao Pedro (Porto U.)
/EC-SLI Collaboration
We report on the lattice location and thermal stability of Fe in n+- and p+-type silicon. By means of emission channeling we have observed Fe on ideal substitutional sites, sites located in between bond-centered (BC) and substitutional sites, and sites displaced from tetrahedral towards anti-bonding sites. [...]

/IS453 Collaboration ; EC-SLI Collaboration
We have studied the influence of electronic doping on the preferred lattice sites of implanted 61Co, and the related stabilities against thermal annealing, in silicon. Using the beta- emission channeling technique we have identified Co on ideal substitutional (ideal S) sites, sites displaced from bond-centered towards substitutional (near-BC) sites and sites displaced from tetrahedral interstitial towards anti-bonding (near-T) sites. [...]

Identification of the interstitial Mn site in ferromagnetic (Ga,Mn)As
/ EC-SLI Collaboration
We determined the lattice location of Mn in ferromagnetic (Ga,Mn)As using the electron emission channeling technique. We show that interstitial Mn occupies the tetrahedral site with As nearest neighbors (TAs) both before and after thermal annealing at 200 °C, whereas the occupancy of the tetrahedral site with Ga nearest neighbors (TGa) is negligible. [...]

Drawing the geometry of 3d transition metal-boron pairs in silicon from electron emission channeling experiments

/EC-SLI Collaboration
Although the formation of transition metal-boron pairs is currently well established in silicon processing, the geometry of these complexes is still not completely understood. We investigated the lattice location of the transition metals manganese, iron, cobalt and nickel in n- and p+-type silicon by means of electron emission channeling. [...]

Emission channeling studies on transition-metal doped GaN and ZnO: Cation versus anion substitution

/EC-SLI Collaboration
The magnetic and electric properties of impurities in semiconductors are strongly dependent on the lattice sites which they occupy. While the majority site can often be predicted based on chemical similarities with the host elements and is usually simple to confirm experimentally, minority sites are far more complicated to predict, detect and identify.

/EC-SLI Collaboration
We have investigated the lattice location of implanted 61Co in silicon. By means of emission channeling, three different lattice sites have been identified: ideal substitutional sites, displaced bond-centered sites and displaced tetrahedral interstitial sites. [...]
