Single-crystal field-effect transistors based on copper phthalocyanine [PDF]
, 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 of up to 1 cm2/Vs combined with a low field-effect threshold were obtained.

Improving post-partum family planning services provided by female community health volunteers in Nepal: a mixed methods study. [PDF]
, 2020 BACKGROUND: Family planning services in the post-partum period, termed post-partum family planning (PPFP) is critical to cover the unmet need for contraception, especially when institutional delivery rates have increased. However, the intention to choose

High-$κ$ field-effect transistor with copper-phthalocyanine [PDF]
, 2011 The use of SrTiO$_3$ dielectrics as high-permittivity insulator in organic thin film field effect transistors (FET) is evaluated. Field-effect transistors with sputtered SrTiO$_3$ and copper-phthalocyanine (CuPc) as semiconducting layer were fabricated. The device preparation was performed in-situ in an ultra high vacuum chamber system.

Unexpectedly Spontaneous Water Dissociation on Graphene Oxide Supported by Copper Substrate [PDF]
arXiv, 2022 Water dissociation is of fundamental importance in scientific fields and has drawn considerable interest in diverse technological applications. However, the high activation barrier of breaking the O-H bond within the water molecule has been identified as the bottleneck, even for the water adsorbed on the graphene oxide (GO).

On the charge transfer between single-walled carbon nanotubes and graphene [PDF]
Applied Physics Letters, 105, 073115, 2014, 2014 It is important to understand the electronic interaction between single-walled carbon nanotubes (SWNTs) and graphene in order to use them efficiently in multifunctional hybrid devices. Here we deposited SWNT bundles on graphene-covered copper and SiO2 substrates by chemical vapor deposition and investigated the charge transfer between them by Raman ...
