چکیده

Field-effect transistors (FETs) fabricated from undoped and Co(2+)-doped CdSe colloidal nanowires show typical n-channel transistor behaviour with gate effect. Exposed to microscope light, a 10 times current enhancement is observed in the doped nanowire-based devices due to the significant modification of the electronic structure of CdSe nanowires induced by Co(2+)-doping, which is revealed by theoretical calculations from spin-polarized plane-wave density functional theory.

Nanowires: properties, applications and synthesis via porous anodic aluminium oxide template

Quasi one-dimensional nanowires possess unique electrical, electronic, thermoelectrical, optical, magnetic and chemical properties, which are different from that of their parent counterpart. The physical properties of nanowires are influenced by the morphology of the nanowires, diameter dependent band gap, carrier density of states etc. Nanowires hold lot of promises for different applications....

High carrier mobility in single ultrathin colloidal lead selenide nanowire field effect transistors.

Ultrathin colloidal lead selenide (PbSe) nanowires with continuous charge transport channels and tunable bandgap provide potential building blocks for solar cells and photodetectors. Here, we demonstrate a room-temperature hole mobility as high as 490 cm(2)/(V s) in field effect transistors incorporating single colloidal PbSe nanowires with diameters of 6-15 nm, coated with ammonium thiocyanate...

Synthesis and Post-growth Doping of Silicon Nanowires

High-quality silicon nanowires SiNWs were synthesized via a thermal evaporation method without the use of catalysts. Scanning electron microscopy and transmission electron microscopy showed that SiNWs were long and straight crystalline silicon with an oxide sheath. Field effect transistors were fabricated to investigate the electrical transport properties. Devices on as-grown material were p-ch...

Ultrasensitive protein detection using lithographically defined Si multi-nanowire field effect transistors.

Low-doped silicon multi-nanowire field effect transistors with high ON/OFF ratio over 10(7) and a low subthreshold swing of 60-120 mV dec(-1) are fabricated using lithographic semiconductor processes. The use of multi-nanowires instead of a single nanowire as sensing elements has shown improved device uniformity and stability in buffer solutions. The device stability is further improved with su...

Ultrathin CdSe Nanowire Field-Effect Transistors

We report the fabrication, and electrical and optical characterization, of solution-liquid-solid (SLS) grown CdSe nanowire field-effect transistors. Ultrathin nanowires (7–12 nm diameters) with lengths between 1 $m and 10 $m were grown by the SLS technique. Al-CdSe-Al junctions are then defined over oxidized Si substrate using photolithography. The nanowires, which were very resistive in the da...
