“…To date, integrating graphene with TMDs, such as MoS 2 , [ 58–61 ] WS 2 , [ 62,63 ] WSe 2 , [ 64 ] and MoTe 2 , [ 57,65,66 ] which possess moderate bandgaps and strong light–matter interaction compared with graphene, has been extensively investigated. High‐performance photodetectors based on graphene/TMD van der Waals (vdW) heterostructures have the typical Schottky barrier, which makes a great contribution to the photoexcited carrier separation due to the presence of the built‐in electric field.…”

The hybridization of two‐dimensional transition metal dichalcogenides (2D TMDs) with other light‐sensitive materials to fabricate the TMD‐based heterostructures is an effective way to boost the overall photoelectric performance of photodetectors. In particular, the alignment of band structure at the interface of the binding materials plays a critical role in optimizing the carrier transfer path and prompting the charge separation rate, which finally lead to the simultaneous improvement of photoresponsivity and response rate and the expansion of detection range. However, the band alignment engineering topic has been barely summarized and reviewed in detail up to today. Herein, a specific review focused on the band alignment strategies and the related charge‐transfer mechanism of the recently developed novel TMD heterostructures for photodetectors is provided. The band structures are classified into four categories according to the targeted function of photodetectors, including that formed by TMDs with zero‐bandgap materials, narrow‐bandgap semiconductors, middle‐bandgap semiconductors, and wide‐bandgap semiconductors. The corresponding band alignment principles and charge‐transfer behaviors are summarized carefully by providing various latest research works as representative examples under each category. Herein, a key reference for applying and extending the fundamental band alignment principles in the design and fabrication of future TMD‐based heterostructural photodetectors is provided.

“…The fabrication and pattering of CNPs on the silicon substrate were carried out as previously reported by the authors [26][27][28][29][30][31]. Briefly, the silicon substrate was first treated in the piranha solution (H 2 SO 4 :H 2 O 2 = 4:1) at 100 ºC for 30 min to create surface -OH groups.…”

“…Recently, the authors reported a facile and scalable chemical vapor deposition (CVD) approach for the growth of multilayer carbon shell on Au nanoparticle [26][27][28]. This process led to the fabrication of multilayer carbon shell encapsulated Au nanoparticles (referred as carbon nanoparticles, CNPs), which preserve the unique optical properties from Au nanoparticle [29,30], and at the same time present the excellent surface chemical properties of carbon shell [31], which make CNPs of promise for future chemical sensor and bio-medicine applications. Nevertheless, for the as-produced CNPs, the surface of carbon shell is highly hydrophobic due to the presence of amorphous carbon (a normal by-product from CVD) and lack of surface functionalities such as carboxyl (-COOH) and hydroxyl (-COH) groups [32].…”

In this paper, we reported the surface modification of multilayer carbon shell-encapsulated gold nanoparticles (Carbon Nanoparticles, or CNPs) via an oxygen plasma treatment approach and their subsequent functionalization with extraneous gold (Au) nanoparticles for Surface-enhanced Raman Scattering (SERS) sensing and DNA immobilization. The oxygen plasma treatment process led to purification of the multilayer carbon shell, reduction of the shell thickness, and derivatization of carbon shell with functional carboxylic groups. This further opens potential opportunities for surface functionalization of CNPs with extraneous Au nanoparticles or λ-DNA fragments, which were both achieved through a well-defined carbodiimide based covalent linking chemistry without removing the CNPs from the substrate. The resulting CNP-Au nanoparticle hybrids as well as the CNP-DNA architectures were characterized using various microscopic and spectroscopic techniques. The CNP-Au nanoparticle hybrids were further used as highly-sensitive SERS substrate for the detection of trace amount water-containing organic molecule. Meanwhile, they were also fundamentally simulated for their plasmonic behavior using discrete dipole approximation (DDA) method to understand the basic Raman enhancement principle. On the other hand, highly-ordered assembly of CNP-DNA architectures were also demonstrated in detail for their great potential in future DNA detection/recognition and bio-device applications.

“…1 Introduction For many years, semiconducting oxides have been widely used in many fields such as lithium-ion batteries [1], photosensitization [2], and gas sensors [3]. Gas sensors based on semiconducting oxides have received widely attentions which get benefit from their low cost, easy fabrication and portability [4].…”
