Characteristic study of ohmic contact alloy layer in InAs/InP quantum dot lasers

Abstract

Embedded systems research around 2000 focused on microcontroller-based system design, real-time operating systems (RTOS), and hardware-software co-design. Applications included consumer electronics, automotive control systems, and industrial automation. This research paved the way for today’s IoT and smart devices.

In the year 2000, software engineering research emphasized object-oriented design, UML modeling, software testing, and maintenance. Programming languages such as Java and C++ gained popularity, and research focused on improving software reliability, scalability, and reuse.
