Architecture‐Driven Functional Coupling in Vertically Aligned Nanocomposites

Advanced Functional Materials, EarlyView.
Vertically aligned nanocomposites define a growth‐engineered architecture in which vertical interfaces, strain fields, defect pathways, and phase connectivity are created simultaneously. This review shows how these architectural features couple ferroic, optical, ionic, electrochemical, and device responses, establishing design rules and open challenges

Bandgap Reference Voltage Generator

, 2007
　　準確的參考電壓源在現今的積體電路系統中扮演相當重要的角色，它能產生一穩定的參考電壓，不因電源電壓及環境溫度的變化而產生太大的變動，以提供系統作為比較或維持電路正常操作之用。參考電壓源的應用相當廣泛，常見用於類比-數位或數位類比轉換器、運算放大器或線性穩壓器中，提供設定輸入或輸出電壓範圍、差動輸入對之電流源偏壓或作為比較器的參考電壓等等。 　　本論文主要目的為設計一可操作在輸入電壓3V-6V而輸出電壓約1.25V的能隙參考電壓產生電路，提供一穩定的參考電壓給低壓降線性穩壓器使用 ...

Ground‐State Charge‐Transfer Doping in Donor–Acceptor Semiconducting Polymers

Advanced Functional Materials, EarlyView.
This work demonstrates controlled ground‐state charge‐transfer complex formation (GS‐CTC) and doping in a series of diketopyrrolopyrrole‐based donor–acceptor semiconducting polymers paired with a π‐conjugated penta‐t‐butylpentacyanopentabenzo[25]annulene “cyanostar” macrocycle. Complementary experimental techniques show how subtle molecular, electronic,

Forward‐Biased Perovskite Photodiodes for In‐Sensor Optical Change Sensing

Advanced Functional Materials, EarlyView.
A forward‐biased perovskite photodiode is introduced as an in‐sensor analog preprocessing unit that uses current balancing between photocurrent and injection current to generate optical changes relative to programmable optical reference levels. The device directly converts reference‐relative optical changes into bipolar current signals, enabling sensor‐
