Single-electron transport driven by surface acoustic waves: moving quantum dots versus short barriers

, 2006
We have investigated the response of the acoustoelectric current driven by a surface-acoustic wave through a quantum point contact in the closed-channel regime.

A 24-GHz CMOS Front-End [PDF]

, 2004
This paper reports the first 24-GHz CMOS front-end in a 0.18-µm process. It consists of a low-noise amplifier (LNA) and a mixer and downconverts an RF input at 24GHz to an IF of 5 GHz.

Dual‐Modulated Vertically Stacked Transistors With Fully Laminated Plate‐Type Architecture Featuring Nanoscale Channel Length

Advanced Science, EarlyView.
A new vertical transistor design with a dual‐modulation strategy is proposed to overcome the limitations of conventional transistors. This architecture uses a micro‐hole patterned electrode and a graphene electrode to enhance channel control and incorporates a leakage blocking layer to suppress off‐state current.

High‐Performance Ambipolar Organic Electrochemical Transistors Based on Diketopyrrolopyrrole‐Dialkoxybithiazole Conjugated Polymers for Single‐component Inverters

Advanced Science, EarlyView.
Two donor‐acceptor conjugated polymers, incorporating diketopyrrolopyrrole (DPP) and dialkoxybithiazole (2Tz) units with ethylene glycol (EG) side chains, exhibit relatively balanced ambipolar organic electrochemical transistor (OECT) performance. This ambipolarity enables the realization of single‐component complementary inverters capable of ternary ...
