Inert Measurement of Nanoscale Surface

量子科学有限公司（QS）是一家屡获殊荣的纳米技术公司，专注于半导体、电子和医疗保健应用的量子点材料的创新、开发和供应。QS开发了infinq (r) LF-QD技术来制造一种新型的无重金属量子点（QDs），这是一种无毒环保的半导体纳米颗粒。我们的技术还包括用于无重金属量子点的表面工程、油墨配方、薄膜涂层和光电二极管制造。QS向客户提供了这些infq (r) LF-QD材料和技术，用于其光电器件，例如红外光电探测器。为了给我们的客户提供最好的材料和最大的设备性能，有必要对我们的纳米材料的表面结构有一个详细的了解。这些信息提供了我们的工艺对所得到的量子点固体的电子能量结构的影响的反馈。这种见解可以通过对纳米颗粒表面的直接测量和表征来获得，但是这些表征是不可能用现成的技术实现的。通过与拥有尖端设施和专业知识的国家物理实验室（NPL）合作，在惰性气氛下转移，装载和测量空气敏感样品，我们的目标是开发直接测量系统来表征短波红外（SWIR）量子点。我们的客户对无重金属的SWIR量子点有很高的需求。克服这些测量挑战将提高QS的产品竞争力，提高客户的设备性能，增加销售额，获得更多的市场份额，并开辟新的市场。

Quantum Science Ltd (QS) is an award-winning nanotechnology company focusing on innovation, development and supply of quantum dot materials for semiconductor, electronics and healthcare applications.QS has developed INFIQ(r) LF-QD technologies to manufacture a new class of heavy metal-free quantum dots (QDs) which are non-toxic and environmentally friendly semiconductor nanoparticles. Our technologies also include surface engineering, ink formulations, film coating and photodiode fabrication for the heavy metal-free QDs. QS has supplied these INFIQ(r) LF-QD materials and technologies to customers for use in their optoelectronic devices, e.g., infrared photodetectors.To provide our customers with the best materials offering the greatest device performance, it is necessary to have a detailed understanding of the surface structure of our nanomaterials. This information provides feedback on the influence of our processes on the electronic energy structure of the resulting QD solids. Such insights can be obtained via direct measurement and characterisation of the nanoparticle surface, but these characterisations are not possible with off-the-shelf techniques.By working with the National Physical Laboratory (NPL) who has cutting-edge facilities and specialised expertise for transferring, loading, and measuring air-sensitive samples under inert atmosphere, we aim to develop the direct measurements systems to characterise short-wave infrared (SWIR) QDs. The heavy metal-free SWIR QDs are in high demand by our customers for applications in the SWIR.Overcoming such measurement challenges will improve QS' product competitiveness, advance customers' device performance, increase sales, gain more market share, and open up new markets.
