Hall effect of quasi-hole gas in organic single-crystal transistors

open access: yes, 2005
Hall effect is detected in organic field-effect transistors, using appropriately shaped rubrene (C42H28) single crystals. It turned out that inverse Hall coefficient, having a positive sign, is close to the amount of electric-field induced charge upon ...

Trojan Horse nanotheranostics with dual transformability and multifunctionality for highly effective cancer treatment. [PDF]

open access: yes, 2018
Nanotheranostics with integrated diagnostic and therapeutic functions show exciting potentials towards precision nanomedicine. However, targeted delivery of nanotheranostics is hindered by several biological barriers. Here, we report the development of a

Surface states and charge accumulation states on reconstructed InAs(001) surfaces

open access: yesSurface Science, 2015
Abstract Using angle-resolved photoelectron spectroscopy, we investigate the electronic structure of InAs(001) surfaces having different stoichiometries, i.e. the indium rich c(8 × 2) / 4 × 2 surface and the arsenic-rich c(2 × 8) / 2 × 4 surface. We also compare surfaces having the same reconstructions but prepared by different techniques; by ion ...

Single-crystal field-effect transistors based on copper phthalocyanine

open access: yes, 2004
Copper phthalocyanine (Cu-Pc) single crystals were grown by physical vapor transport and field effect transistors (FETs) on the surface of these crystals were prepared. These FETs function as p-channel accumulation-mode devices. Charge carrier mobilities

Review of Streamer Dynamics and Surface Charge Accumulation on Ice Surfaces

open access: yesElectrical and Electronic Engineering, 2013
This paper rev iews the main contributions of the CIGELE research team to the dynamics of streamer d ischarges along ice surfaces. These investigations were main ly performed under lightning impulse voltage, in at mospheric air. High-speed streak photography techniques were used to observe the streamers propagating between a rod-plane configuration ...
