SGER: Self-Assembled Guanosine Based Hybrid Single Molecular Electronic Devices

我们在拟议的探索性研究计划的目标是开发：i。基于自组装修饰鸟嘌呤半导体固定在GaN半导体衬底上的纳米分子电子二极管。这项工作包括优化材料特性，通过增加鸟苷单分子链的长度来提高器件性能。它将使大规模的纳米分子电子器件的制造使用传统的光刻技术。 二. GaN上的场效应晶体管或光电探测器，在紫外可见光区具有增强的效率。我们还将通过改变DNA碱基配对和将合成核苷酸掺入DNA来扩展该设备的功能，以检查双链DNA的电化学性质。智力价值和更广泛的影响：在生物分子中，DNA在生物过程中具有基本作用。分子生物学（用于设计具有所需功能和/或自组装特性的DNA）和微电子技术（用于器件制造）的结合因此成为实现新型纳米电子元件的工具。由于这是一个广泛的跨学科项目，我们打算联合收割机，并建立在我们的优势，在先前的成果的开发和表征的GaN基材料/设备和定制寡核苷酸分子沿着与我们的合作者的建立能力共轭功能化聚合物的生物分子在密歇根州分子研究所。 该团队将包括一名学生，他将接触到这个多方面项目的所有阶段。在UNT，目前有一个NSF研究经验的本科生计划，将通过这项拟议的研究得到加强。PI将根据拟议工作的成功在UNT提供一个关于软凝聚态物理的重点课程。

Our objective in the proposed exploratory research program is to develop:i. Nanoscale molecular electronic diodes based on self-assembled modified guanosinesemiconductor immobilized on a GaN semiconductor substrate. This effort includes optimization of the material characteristics to improve device performance by increasing the length of a single molecular chain of guanosine. It will enable large-scale fabrication of nanoscale molecular electronic device using conventional photolithography techniques. ii. Field-effect transistor or photo-detectors on GaN with enhanced efficiency in the ultraviolet visible region. We will also extend this device functionality to examine electrochemical properties of double-stranded DNA by altering DNA base-pairing and incorporating synthetic nucleotides to DNA.Intellectual merit and Broader Impact:Among biomolecules, DNA has a fundamental role in biological processes. The combination ofmolecular biology (for engineering DNA with the desired functional and/or self-assemblingproperties) and microelectronic technology (for device fabrication) thus becomes the tool to realize a new class of nanoelectronic element. Since this is a vastly interdisciplinary project, we intend to combine and build upon our strength in prior achievements of development and characterization of GaN based materials/devices and tailoring oligonucleotide molecules along with our collaborator's established capability of conjugating functionalized polymers to biomolecules at Michigan Molecular Institute. This team will include a student, who will be exposed to all phases of this multifaceted project. At UNT there is currently an NSF Research Experience for Undergraduates program that will be enhanced by this proposed research. The PI will offer a focused course on soft condensed matter physics at UNT based on the success of the proposed work.
