Growth and characterization of Fe nanostructures on GaN

Structural and magnetic properties of ultra-thin Fe films on metal-organic chemical vapour deposited GaN(0001)

“…The disappearance of the RHEED patterns suggested a 3D Volmer-Weber type islands growth of the Fe films. 8,13 RHEED streaks re-emerged when thickness increased to above 2 nm as shown in insets (f-i). The streaks were broader than the original GaN streaks.…”

“…3. All patterns were recorded with an incident electron beam along the a-axis [11][12][13][14][15][16][17][18][19][20] of GaN(0001). As shown in inset (a), the GaN(0001) surface showed clear 1 x 1 RHEED pattern with Kikuchi arcs indicative of a smooth and long-range ordered crystalline surface.…”

Iron on GaN(0001) pseudo-1 × 1 (1+112) investigated by scanning tunneling microscopy and first-principles theory

“…Several groups have reported studies of Fe on Gapolar wurtzite GaN grown by molecular beam epitaxy (MBE). [19][20][21][22] A few studies were focused on looking at the initial phase of growth, especially sub-monolayer (sub-ML) Fe deposition. 22,23 He et al reported scanning tunneling microscopy (STM) studies of ultra-thin layers of Fe on bulkterminated GaN(0001) 1 Â 1 and on GaN(0001) pseudo-1 Â 1, and in the latter case an Fe-induced [0.…”
