Benefits of technology

This patent describes a device that can detect light and a structure called a phototransistor that can detect changes in light. The device includes a special material called a polyfluorinated dibromo-platinum(II) diimine complex, which is located in a channel formed between two metallic electrodes. The device can be used to create a more efficient and sensitive photodetection system.

Problems solved by technology

However, conventional inorganic PDs have a low strain tolerance and are limited to rigid substrates and gradual electrical changes, in which large mechanical strain can lead to the deterioration of the spectral response or result in device failure.
Despite being an outstanding material for various applications, the stability and electrical properties of the organic semiconductors currently used in the various PD are not yet suitable.
Generally, the organic semiconductors that have been tried for various PDs are limited by the low carrier mobility and high threshold voltage due to the carrier scattering caused by impurities, structural defects, and grain boundaries, which hinder the development and integration of these materials for high-performance and low-cost applications.

Embodiment Construction

[0024]The following description of the embodiments refers to the accompanying drawings. The same reference numbers in different drawings identify the same or similar elements. The following detailed description does not limit the invention. Instead, the scope of the invention is defined by the appended claims. The following embodiments are discussed, for simplicity, with regard to a single-crystal linear-chain polyfluorinated dibromo-platinum(II) diimine based photodetector. However, the embodiments to be discussed next are not limited to a photodetector, but may be applied to other optical devices.

[0025]Reference throughout the specification to “one embodiment” or “an embodiment” means that a particular feature, structure or characteristic described in connection with an embodiment is included in at least one embodiment of the subject matter disclosed. Thus, the appearance of the phrases “in one embodiment” or “in an embodiment” in various places throughout the specification is not...

Abstract

A photodetection device is configured to detect light and the photodetection device includes a substrate having a largest surface; a dielectric formed over the largest surface of the substrate; a first metallic electrode formed on the dielectric; a second metallic electrode formed on the dielectric, at a given distance from the first metallic electrode, to form a channel; and a single-crystal linear-chain polyfluorinated dibromo-platinum(II) diimine complex located in the channel.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to U.S. Provisional Patent Application No. 62 / 908,683, filed on Oct. 1, 2019, entitled “HIGHLY AIR-STABLE, WATER-RESISTANT AND FAST RESPONSE ORGANIC PHOTODETECTORS BASED ON A SINGLE CRYSTAL PT COMPLEX,” the disclosure of which is incorporated herein by reference in its entirety.BACKGROUNDTechnical Field[0002]Embodiments of the subject matter disclosed herein generally relate to a photodetector that has a fast-response, is highly stable in air, and is water resistant, and more particularly, to a photodetector that has the active layer made of an organic single crystal having a lamellar molecular structure.Discussion of the Background[0003]Photodetectors (PDs) are sensors that detect electromagnetic radiation (e.g., light) and are at the core of many technologies, for example, chemical and biological analyses, combustion flame monitoring, image sensors, remote controls, optical communications, night vision, ...
