Nanoarhitecturi în bază de GaN şi matrici tridimensionale din materiale biologice pentru aplicaţii în microfluidică şi inginerie tisulară | Journal: | Journal of Engineering Science | Abstract: | In this paper, the design and elaboration of a cost-effective technological process for the fabrication of the platform for the study of flexoelectric properties of GaN microtubes with the diameter of 2 - 5 μm and the thickness of the microtube walls of 50 nm is proposed. The impact of the design as well as the electrochemical etching parameters (applied voltage, duration of anodization) on the obtained channel dimensions is investigated. The proposed technological route implies electrochemical etching of n-InP semiconductor crystal in an environmentally friendly electrolyte at high etch rate. The technological process was optimized experimentally. It was proposed to introduce a perpendicular channel in which the microtube will be placed to reach a higher stability on the platform during the measurements. |
