Printed Perovskite LEDs

Microelectronics utilize various functional materials whose properties make them suitable for specific applications.    For example, transistors and data storage devices are made of silicon, and most photovoltaic cells used for generating electricity from sunlight are also currently made of this semiconductor material.    In contrast, compound semiconductors such as gallium nitride are used to generate light in optoelectronic elements such as light-emitting diodes (LEDs). The manufacturi...
