“…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.

“…However, though with highly negative charge storing capability, the practicality and popularity of these traditionally used dielectric frictional polymer materials are usually limited due to its inherent low current density output [19]. To address these challenges, the integration of semiconductors [20] with competitive electronic conductivity into TENGs becomes an outstanding approach for robust TENG formation. These schemes can facilitate charge transition thereby optimizing electrical output performances.…”

Low-cost, handily prepared, and efficient large-scale triboelectric nanogenerator (TENG) is considered as the new scheme for distributed mechanical conversion or renewable blue energy utilization. Semiconductors with high carrier mobility introduction potency overcome pure polymer restriction for uncompetitive short current density. An extremely popular all-inorganic lead-free double perovskite Cs2AgBiBr6 (CABB) has emerged as extraordinary potential material in the substitution of semiconductor triboelectric material, which overcomes the limitations of high impedance associated with organic polymer insulator-based materials. In this current study, assembled by CABB which was certified as an available positive frictional material, TENG with a sandwiched structure of ITO/c-TiO2 (compact TiO2)/m-TiO2 (mesoporous TiO2)/CABB - the poly tetra fluoroethylene (PTFE)/Al exhibits appropriate performance on environmental stability and output capacity. A comparison of the fabrication process showed that spraying is an inexpensive method to prepare large-scale functional films of CABB TENG with brilliant relative dielectric constant and work function (Wf) difference that possess more distinguished output characteristics. This was confirmed by the appearance of higher open-circuit voltage of 105 V, larger short-current density of 2.45 mA/m2 at 0.25 Hz motion parameter, and more abundant power density output of 0.76 W/m2 under a higher frequency of 10 Hz. Further study clearly confirmed that both higher frequency and larger contact area are conducive to the total output power, while terminal charging speed is inversely or positively proportional with capacitance or mechanical frequency. The final physical display effect showed that spraying with CABB TENG could light up at least 53 commercial yellow LEDs, holding decent energy conversion ability. This confirms its efficiency, high throughput, and cost efficiency.
