Deterministic Nucleation of Nanocrystal Superlattices on 2D Perovskites for Light‐Funneling Heterostructures

Advanced Materials, EarlyView.
This work investigates the heterogeneous nucleation of CsPbBr3${\rm CsPbBr}_3$ nanocrystal superlattices along the faces of 2D PEA2PbBr4${\rm PEA}_2{\rm PbBr}_4$ layered perovskite microcrystals. Core–crown and core–shell heterostructure morphologies are obtained.

Photo-EMF Sensitivity of Porous Silicon Thin Layer–Crystalline Silicon Heterojunction to Ammonia Adsorption

Sensors, 2011
A new method of using photo-electromotive force in detecting gas and controlling sensitivity is proposed. Photo-electromotive force on the heterojunction between porous silicon thin layer and crystalline silicon wafer depends on the concentration of ...

Systematic Phosphorus-Driven Structural and Field Engineering of n-a-Si:H for Flexible n-a-Si:H/Te Near-Infrared Photodetectors. [PDF]

Adv Sci (Weinh)
Our research elucidates the systematic evolution of the microstructure and optoelectronic properties of n‐a‐Si:H governed by the phosphine dilution ratio. Optimally phosphorus‐doped n‐a‐Si:H is integrated with Te to form a flexible heterojunction, enabling high‐performance near‐infrared photodetectors.

A Universal van der Waals Tunneling Injector for Monolayer CMOS

Advanced Materials, EarlyView.
A universal van der Waals injector unlocks polarity‐flexible tunneling contacts for monolayer CMOS. SnSe2, an intrinsically degenerate 2D semiconductor, establishes polarity‐specific band alignments with both WSe2 and MoS2 channels, enabling steep switching, high on/off ratios, and a unified route to low‐power 2D logic.

Nanocrystalline Silicon Oxide in Silicon Heterojunction Solar Cells

, 2018
To advance the contribution of photovoltaic (PV) systems in a transition towards fully sustainable energy generation, the costs of the associated systems need to decrease. In particular, a constant evolution of their solar energy conversion efficiency ($\eta$) is an effective way to reduce the overall costs of the energy production of a solar cell.
