Figure 1a

The exemplary GaN needle-like and plate-like single crystal habits.

Figure 1b

The exemplary GaN needle-like single crystal habits [2].

Figure 2

The observed GaN plate-like single crystal habits and their longitudinal sections; habits: a) without pyramidal faces, b) with pyramidal faces {101}, c) with pyramidal faces {102}, d) with both sets of pyramidal faces. The letter "s" indicates the line of longitudinal section; m6, m16 denote growth bands.

Figure 3a

The observed GaN needle-like single crystal habits with pyramidal faces {101}. The letter "s" indicates the line of longitudinal section shown in Figure 3b.

Figure 3b

The longitudinal section of GaN single crystal habit shown in Figure 3a, with pyramidal faces {101}. m3, m30 denote growth bands.

Figure 4

Two kinds of the observed GaN needle-like single crystal habits and their longitudinal sections; habits: a) with pyramidal faces {102}, b) with both sets of pyramidal faces {101} and {102}. The letter "s" indicates the line of longitudinal section.
