Dielectric layer structure and performance

CLEARink显示公司是一家温哥华技术初创公司，开发新的显示技术。他们的技术是液晶显示器和有机发光二极管的一种替代方案，它们的功耗很高。CLEARink开发了一种新型的反射显示技术，该技术可以提供**的视频速率和超低功耗。他们的技术是基于在流体中使用带电粒子来控制其新型反射膜对环境光的反射率。当带电粒子在反射膜附近时，反射率受到阻碍，从而提供图像对比度。对带电粒子位置的控制是通过对沉积在其专有反射器上的薄导体和介电层施加小电压来实现的。对粒子位置和迁移率的精细控制对显示性能至关重要，但会受到导体和介电层性质的影响。CLEARink正在寻求进一步优化这种控制，以提高对比度和设备响应时间。在这里，我们建议通过研究介电薄膜的材料特性及其与显示性能的关系来解决这些问题。SFU 4D实验室的制造和表征能力，加上我们在表面科学和材料化学方面的专业知识，使与CLEARink的合作成为理想的伙伴关系。使用扫描电子显微镜、x射线衍射、x射线光电子能谱、原子力显微镜和接触角测量，将评估介电层的质量与器件性能的关系。我们**将与CLEARink技术人员密切合作，研究不同厚度介质膜的器件性能，以及介质膜**在哪些地方通过进一步的化学改性进行了进一步改性。该项目的预期结果是**为CLEARink提供对其显示特性的改进控制，并加速其商业化生产的道路。这将通过增加就业机会、创造财富，为加拿大提供更广泛的利益，并为进一步的高科技发展机会铺平道路。

CLEARink Displays Corporation is a Vancouver technology start-up developing new display technology. Their**technology is an alternative to liquid crystal displays and organic light emitting diodes which operate with**significant power consumption. CLEARink has developed a novel reflective display technology that offers**video rate capability with ultra-low power consumption. Their technology is based on the use of charged**particles in a fluid to control the reflectivity of ambient light from its novel reflector films. When charged**particles are in the vicinity of the reflector film, reflectivity is hindered, providing image contrast. Control over**of the charged particle location is achieved by applying small voltages to thin conductor and dielectric layers**deposited onto their proprietary reflectors. Fine control of particle location and mobility in response to the**applied fields is critical for display performance, but can be affected by the properties of the conductor and**dielectric layers. CLEARink is seeking to further optimize this control in order to improve contrast, and device**response time. Here, we propose to address these issues by examining the materials properties of the dielectric**thin films and their connection to display performance. The fabrication and characterization capabilities**available at SFU's 4D LABS in conjunction with our expertise in surface science and materials chemistry make**this partnership with CLEARink ideal. Using scanning electron microscopy, x-ray diffraction, x-ray**photoelectron spectroscopy, atomic force microscopy, and contact angle measurements, the quality of dielectric**layers will be assessed in relation to device performance. Working closely with CLEARink technical staff, we**will investigate device performance with dielectric films of different thickness, and where the dielectric films**have been further modified through further chemical modification. The expected outcomes of this project are to**provide CLEARink with improved control over their display characteristics and to accelerate their path to**commercial production. This will provide broader benefits to Canada through enhanced employment**opportunities, wealth generation, and pave the way for further high technology development opportunities.
