Estimating Potential Demand and Customers' Perception of Service Value in a Two-station Service System [PDF]

arXiv
The potential demand in the market and customers' perception of service value are crucial factors in pricing strategies, resource allocation, and other operational decisions. However, this information is typically private and not readily accessible. In this paper, we analyze a service system operating across two stations, each with its own customer ...

Buried Interface Regulation with a Supramolecular Assembled Template Enables High‐Performance Perovskite Solar Cells for Minimizing the VOC Deficit

Advanced Materials, EarlyView.
Self‐assembled amphiphilic phosphonate‐based supramolecule functions as a perovskite crystallization‐driven template at SnO2/perovskite buried interface, which induces a highly preferred (100) orientation toward out‐of‐plane direction, facilitates carrier extraction and transfer, passivates the intrinsic defects, and achieves a promising efficiency of ...

Ultralow Voltage Operation of p‐ and n‐FETs Enabled by Self‐Formed Gate Dielectric and Metal Contacts on 2D Tellurium

Advanced Materials, EarlyView.
This work presents atomically controlled material transformations in 2D Te for near‐ideal FETs, featuring low‐resistance NiTex‐Te contacts and ultraclean TiOx‐Te gate dielectrics (0.88 nm EOT). A record‐low SS of 3.5 mV dec−1 is achieved at 10 K, and 2D Te‐based CMOS inverters operate at 0.08 V, enabling energy‐efficient IC technologies.

Recent Advances in Wide‐Bandgap Perovskite Solar Cells

Advanced Materials, EarlyView.
Ubiquitous defects predominately account for photo‐instability and open‐circuit voltage losses in wide‐bandgap perovskite solar cells (WBG PSCs). This review comprehensively presents the underlying impact mechanisms, summarizes the advanced optimization strategies across various functional layers and their interfaces to develop efficient and stable WBG
