    Advanced Optical Materials, 2026
    Advanced imaging, sensing, andtelecommunications demand high‐performance, low‐power broadband photodetectorswith improved responsivity and spectral range. This work fills a key gap bydemonstrating p‐Si/n‐Sn(S x Se 1‐x ) 2 verticalheterojunction (HJ) photodetectors with asymmetric Ag (Φ = 4.28 eV) /graphene(Φ = 4.7 eV) electrodes to optimize carrier dynamics and band alignment. Fourdevice configurations; symmetric (D1: Ag/HJ/Ag, D2: Gr/HJ/Gr) and asymmetric(D3: Gr/HJ/Ag, D4: Ag/HJ/Gr) were systematically investigated to elucidate therole of electrode asymmetry in enhancing photoresponse. D4 achievesstate‐of‐the‐art responsivity of 1.01 A/W, external quantum efficiency (EQE) of 197.29%, and specific detectivity of 3.75 × 10 11 Jones at 635 nm(130 µW/cm 2 , +3 V), driven by efficient hole injection at Ag/p‐Si (Φ Bp ≈ 0.87 eV) and electron extraction at Gr/n‐SnSSe (Φ Bn ≈ 0.38 eV), augmented by photoconductive gain from trap‐assisted carrier multiplication.The D3 device operates self‐powered, producing 16.6 nA at 0 V under white lightdue to a strong built‐in field from the Gr/Ag work‐function contrast. Thedevices show broadband response (505–940 nm) with high sensitivity performanceeven at low light intensities (<150 µW/cm 2 ). This work presentsa scalable, material‐efficient route to high‐efficiency self‐poweredphotodetectors for energy‐efficient broadband sensing.

  • Layered Heterostructures Based on MoS2/MoSe2 Nanosheets Deposited on GaN Substrates for Photodetector Applications
    Sukhendu Maity, K. Sarkar, Praveen Kumar
    ACS Applied Nano Materials, 2023
    Due to the advanced properties of layered 2D materials, their heterostructuring with conventional 3D semiconductors is one of the promising ways to design efficient and affordable optoelectronic devices. However, systematic studies on designing 2D/3D heterojunctions with a focus on enhancing the photodetection properties are sparse in the literature. In this report, we present systematic experimental and theoretical investigations on 2D MoS 2 /MoSe 2 heterostructuring with modified GaN substrates for designing efficient photodetectors. We achieved a gradual increment in photocurrent by engineering MoS 2 and MoSe 2 as single/double heterojunctions on GaN substrates. Time-correlated single-photon counting (TCSPC) results infer significant improvement in the lifetimes of the photoexcited charge carriers for the optimized MoS 2 /MoSe 2 /e-GaN heterostructure-based photodetectors. Interestingly, photodetectors designed with double heterojunctions that maintain type-II band alignment (e-GaN/MoSe 2 /MoS 2 ) exhibit the highest photoresponsivity of 82 A/W, specific detectivity of 1.79 ×10 14 Jones, external quantum efficiency of 27,880%, and stability for over 6 months in a laboratory testing environment under the illumination of 365 nm. Density functional theory (DFT) simulations establish the superiority of double heterojunctions with staircase band alignment for efficient charge carrier transport. This study provides fundamental insights on optimizing the band alignment for desired photodetection concerning 2D/3D integration, which can be exploited for other hybrid integrated systems and applications.
