structure, we should consider non ideal effects when measure the capacitance according to applied voltage. They are 'fixed charge', 'mobile charge', and 'surface states'. When the fixed charge exists in oxide layer, it causes entire curve of graph to shift to the [Figure 12] C-V graph shift by direction of bias

layer/graphene had low contact resistance of 0.7~1.2Ω/cm2, and we could achieve better luminance for GaN-based LED. However, for patterned Ni layer/graphene electrode, we failed to measure the contact resistance.
Structure of GaN based LED : ‘Top emission’ and ‘Vertical’ structures
Since achieving heavily doped p-GaN is difficult, it is hard for p-GaN in top emission LED to spread
It is evident that Ticket Monster is organic structure. Span of control is small for three departments, except sales department. The superior manages less than twenty subordinates. Sales department is composed of one hundred forty members, however, it has efficient team system. Each team has only seven members, therefore, it is small group. The entire organization is made up of four layers, so it
