Preparation and characteristics of Cu/Al2O3/MgF2/Au tunnel junction

Abstract

The fabrication process of Cu/Al 2 O 3 /MgF 2 /Au double-barrier metal/insulator/metal junction (DMIMJ) was introduced, and more stable light emission from this junction was successfully observed. The light emission physical mechanism of the junction was discussed. Results show that light emission spectrum of this structure locates at wavelength of 250-700 nm with two peaks at around 460 nm and 640 nm, which moves towards shorter wavelength region in comparison with that of the Al/Al 2 O 3 /Au junction. The light emission efficiency of this junction ranges from 0.7×10 -5 -2.0×10 -5 , which is 1 to 2 orders higher than that of the single-barrier Al/Al 2 O 3 /Au junction. The improved properties of this structure should be due to the electrons resonant tunneling effect in the double-barrier.

Deoxidation of Electroslag Remelting (ESR) – A Review

“…The loss of Si and Mn was prevented and low Al content ( < 0.01 mass%) in steel was kept during ESR for 180 tonne-scale 26Cr2Ni4MoV steel production when using Ca-Al deoxidation for the earlier stage and Al deoxidation for the later stage. 11) Wang et al 88) confirmed that the loss of Si and Mg in CrNiMoV steel was prevented in the case of ESR using Al for slag deoxidation, meanwhile homogeneous distribution of Al content in the ESR ingot was obtained.…”

Size effect on mechanical behavior of Al/Si3N4 multilayers by nanoindentation

“…Nanoscale multilayered composites exhibit distinct electrical [1][2][3], magnetic [4], optical [5,6] and mechanical properties [7][8][9][10], and therefore have attracted an increased research attention for more than a decade [11][12][13][14][15][16]. Increasing interest is also paid on the investigation of mechanical properties of the multilayered composites due to the implication on the reliability issue in the applications.…”

Synthesis and optoelectronic properties of p-type nitrogen doped ZnSe nanobelts

“…One-dimensional (1D) inorganic nanostructures such as nanowires (NWs), nanobelts (NBs), and nanotubes (NTs) have been studied extensively with respect to fundamental properties and potential applications in nanoscale devices [1][2][3][4][5][6][7][8]. They are expected to play important roles as the key units of nextgeneration nanoscale electronic, optoelectronic devices.…”
