Development of Gallium Nitride Based Interfaces
Abstract
The proposed work aims to fabricate hybrid semi condutor/biomolecular platfonn. The purpose of the platform will be to: i) guide the placement, growth and spreading of neuronal cells using surface anchored molecular cues; ii) quantify interactions among the different surface properties (morphological, biochemical, and adhesion) and neuronal cells at sub-upm scales; iii) develop integrated bioelectronic devices based on the coupling between neuronal cells and novel inorganic semiconductor platforms. The proposed work will deduce knowledge necessary to produce reliable bioelectronic interfaces that determine organism behavior. To understand the influence of surface properties on guiding neuronal growth, the following aims are proposed: Aim I: Fabricate monotonic gradients with different surface chemistry, adhesion and nanoscale characteristics based on the ternary nitrides, AIGaN and lnGaN. Fabricate structures of periodic variation in the polar orientation based on the ternary alloys. Aim 2: Utilize the gradient semiconductor surfaces to direct the behavior of growth cones using cooperative effects. Aim 3: Integrate the engineered semiconductor surfaces into a platform to quantify neuron/surface chemical interactions before and after electrical stimulation.
