"The Contradictions of Export-led Growth" [PDF]

open access: yes
The export-led growth paradigm is a development strategy aimed at growing productive capacity by focusing on foreign markets. It rose to prominence in the late 1970s and became part of a new consensus among economists about the benefits of economic ...

Memristor‐Driven Active‐Matrix Organic Light‐Emitting Diode for Energy Efficient and High‐Resolution Displays

open access: yesAdvanced Functional Materials, EarlyView.
This study demonstrates that memristors can replace conventional 2T–1C driving circuits with simplified 1T–1 m architectures by exploiting resistance switching. With ultra‐low switching voltages (< ±0.2 V) and multi‐level resistance states, the memristors precisely control the current injected into organic light‐emitting diodes (OLEDs).

Rationally Designed Bilayer Passivation Strategy for High‐Performance Vacuum‐Processed Perovskite Solar Cells

open access: yesAdvanced Functional Materials, EarlyView.
A bilayer “Anchor‐and‐Seal” passivation strategy using EDAI2 and 4MeO‐PEAI effectively mitigates surface defects in vacuum‐processed perovskite films through synergistic hydrogen bonding and Lewis base coordination. This approach optimizes interfacial energy alignment and suppresses non‐radiative recombination, enabling vacuum‐deposited p‐i‐n ...

Simulation And Analysis Of Spectrum And Flux Of LED

open access: yes, 2012
[[abstract]]This thesis presents a compact test system to measure the spectrum and flux of unknown LED. Once we get these two parameters, we can reconstruct the LED model by using the optics simulation software TracePro to interactively verify the ...
