Photodetectors of 2D Materials from Ultraviolet to Terahertz Waves

Abstract: 2D materials are considered to be the most promising materials for photodetectors due to their unique optical and electrical properties. Since the discovery of graphene, many photodetectors based on 2D materials have been reported. However, the low quantum efficiency, large noise, and slow response caused by the thinness of 2D materials limit their application in photodetectors. Here, recent progress on 2D material photodetectors is reviewed, covering the spectrum from ultraviolet to terahertz waves. First the… Show more

“…[ 4–6 ] In the past decade, 2D layered materials have attracted increasing attentions in a variety of fields because of their unique and extraordinary physical properties. [ 7–9 ] For example, the family of transition metal dichalcogenides (TMDs) and TMDs based van der Waals (vdW) heterostructure have demonstrated great success in light sensing, video recording and optoelectronic circuits. [ 10–12 ] However, most of these 2D materials possess high‐symmetry in‐plane lattice structure and have been exploited into non‐polarization dependent devices.…”

“…Recently, novel photodetectors based on 2D materials and 2D vdW heterostructures have received extensive attention [64], which are divided into photoconductors, phototransistors, and photodiode-based on the device structures. The key parameters include photoresponsivity (R), external quantum efficiency (EQE), the response time (τ ), and photodetectivity (D * ) [63,65]. In the early layered-materials-based photodetectors, the R value was only a few mA/W [20].…”

“…Graphene, a pioneer of two-dimensional materials, has attracted great scienti c interests due to its excellent physical and chemical properties since its discovery by Andre Geim's group 1 . An extensive research on the properties of the material has led to many novel applications, such as exible devices [2][3][4][5][6] , transparent electrodes [7][8][9][10][11][12][13] , ultra-fast photodetectors [14][15][16][17] and wearable temperature sensors [18][19][20] by taking advantage of graphene's high transmittance (e.g. visible light transmittance of 97.7% 21 ), exibility, conductivity (e.g.…”
