Summary The new field of applications for triboelectric materials is based on the combination of high physical durability and charge properties of ZnO semi‐conductor thin films, which have been explored in this work. ZnO films are successfully deposited by the RF magnetron sputtering method in the wurtzite phase. A post‐heat‐treatment process of the as‐deposited films is carried out in an oxygen atmosphere at 973 K. According to the X‐ray diffraction patterns, scanning electron microscope (SEM), and atomic force microscopy (AFM) images, the average particle size of the ZnO films increases gradually with the heat‐treatment process. The semilogarithmic current‐voltage and frequency‐dependent capacitance measurements of thin films under various bias voltages are done to understand the charge transfer resistance, conductivity and capacitance properties which directly affect the figure of merit (FOMm) of the triboelectric layer material performance. The charge density and triboelectric charge density values in present study for heat‐treated thin films are 11 and 121 mC/m2, respectively. These findings might be used as a good candidate for further triboelectric device energy research areas in the near future.

“…Nevertheless, friction materials treated by these methods tended to be less stable. In recent years, researchers found that semiconductors can also produce charge transfer by rubbing against another material and could generate direct current (DC) with high density, which gives them an advantage over conventional TENGs. − Therefore, the triboelectrification phenomenon between semiconductors has been given more and more attention. − It is noteworthy that the third-generation semiconductor materials (for instance, gallium nitride (GaN)) have the characteristics of large bandgap width, high breakdown field strength, and high electron saturation speed, which can achieve excellent output performance for nearly two years as a new friction materials. − …”

With the rapid development of technology and the expansion of the information age, self-powered systems are gradually emerging. Triboelectric nanogenerators (TENGs), coupling contact electrification and electrostatic induction, can realize continuous power supplied for small devices by converting energy. Traditional TENGs mainly used organic polymer insulators as triboelectric materials, which are limited by low current density alternating current. Recently, many different semiconductor material systems, especially gallium nitride (GaN), have been tried for better electric output performance or more application potential due to their high current density direct current, which can improve the output performance and mechanical properties of TENGs and have important application value at the forefront of portable electronic devices, Internet of things, environmental and infrastructural monitoring, medical science, security, and other fields. In this review, we summarize the latest research achievements and progress on TENGs with different semiconductor structures, including metal–semiconductor TENGs, semiconductor–semiconductor TENGs, metal–insulator–semiconductor TENGs, and liquid–semiconductor TENGs. On the basis of the current TENG theory of tribovoltaic effect, the generation mechanism and performance of each TENG was represented. Direct-current TENGs based on semiconductor structure show great promise for self-powered electronic devices.
