PEDOT: PSS thin films are widely used as transparent coatings in flexible semiconductor devices including solar cells. However, they are not widely used as transparent coatings in combination with crystal substrates. This work shows the possibility of usi... see more

The paper presents the results of studies of the optical and electrical properties of ??Ox/n-Cd1-?Zn?Te semiconductor heterojunctions made by depositing MoOx films on a pre-polished surface of n-Cd1-?Zn?Te plates (5 × 5 × 0.7 mm3) in a universal vacuum in... see more

The cutoff frequency performance of an NPN Si/SiGe/SiGe single-heterojunction bipolartransistor (SiGe SHBT) at high collector current densities has been analysed using a 2-D MEDICIdevice simulator. A conventional NPN Si/SiGe/Si double-heterojunction bipol... see more

In this work, an III-V tunneling field-effect transistor (TFET) with source and channel heterojunctions is proposed and introduced. Proposed structure combine the high tunneling efficiency induced by heterojunction material and the high mobility of III-V ... see more

CuBi2O4/CeO2 composite materials were synthesized by solid state method and were characterized by a number of techniques such as X-ray diffraction, scanning electron microscopy and UV–Vis diffuse reflectance spectroscopy. The photocatalytic activity of th... see more

In the current work, we report a facile synthesis of n-SnO2/p-NiO nanowire heterojunctions by a drop-coating approach. The pure SnO2 and NiO nanowires (NWs) were grown by chemical vapor deposition (CVD) and hydrothermal methods, respectively. Morphology, ... see more

The enhancement of light absorption and photoluminescence quenching properties of the bulk heterojunction systems which were fabricated using poly(N-vinylcarbazole) (PVK); poly(N-hexylthiophene)(P3HT) and fullerene derivative 1-(3-methoxycarbonyl) propyl-... see more

We report a room-temperature (RT) hydrogen gas (H2) sensor based on palladium-decorated single-walled carbon nanotube/Si (Pd-SWNTs/Si) heterojunction. The current-voltage (I-V) curves of the Pd-SWNTs/Si heterojunction in different concentrations of H2 wer... see more

In this paper we reveal electrical detection properties of planar MBE grown GaAs/Al0.25Ga0.75As heterojunction diode at different ambient temperatures. These investigations enabled to reveal the reasons of voltage signal rise across the heterojunction dio... see more
