The semiconductor direct‐current triboelectric nanogenerator (SDC‐TENG) based on the tribovoltaic effect is promising for developing a new semiconductor energy technology with high power density. Here, the first SDC‐TENG built using gallium nitride (GaN) and bismuth telluride (Bi2Te3) for ultrahigh‐power generation is reported. During the friction process, an additional interfacial electric field is formed by continuous contact electrification (CE), and abundant electron–hole pairs are excited and move directionally to form a junction current that is always internally from Bi2Te3 to GaN, regardless of the semiconductor type. The peak open‐circuit voltage can reach up to 40 V and the power density is 11.85 W m−2 (average value is 9.23 W m−2), which is approximately 200 times higher than that of previous centimeter‐level SDC‐TENGs. Moreover, compared to traditional polymer TENGs under the same conditions, the average power density is remarkably improved by over 40 times. This study provides the first evidence of CE on the tribovoltaic effect and sets the normalized power density record for TENGs, which demonstrates a great potential of the tribovoltaic effect for energy harvesting and sensing.

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.
