Hexagonal CdTe-Like Rods Prompted from Bi₂Te₃ Droplets

Correlation of microscopic grain evolution in post‐CdCl 2 annealing and performance of CdS/CdTe thin‐film solar cells fabricated using pulsed laser deposition

“…Meanwhile, the passivation of grain boundaries and reduction of voids between neighboring grains tend to hamper the lateral growth and improve the compactness of the CdTe film. Finally, it is well known that CdTe with a structure of hexagonal always has asymmetric rod-shaped particle [38,39]. Considering the surface morphology of the CdTe films before and after annealing always has spherical or symmetric-shaped grains as shown in AFM images, this observation further suggests the cubic phase is predominant in the PLD CdTe thin films.…”

Self-Catalyzed CdTe Wires

“…This reduced non-radiative recombination makes these ideal for many device applications such as radiation detectors and PV. In order for a direct comparison between the CL signals both were renormalized ( Figure 5 f) to their respective highest intensity signals, both CL spectra for the wires and planar film show a near band edge transition [ 11 ]. The peak for wires is shifted to a slightly higher energy of 1.435 eV compared to 1.419 eV for the planar film, these peaks correspond to a typical donor-acceptor pair transition observed for CdTe [ 3 , 5 ].…”

“…The use of catalysts is problematic when attempting to create device quality material. Au and Bi have been used to successfully synthesize CdTe wires [ 9 , 10 ], however both have been established as deep level recombination centers in CdTe, compromising performance [ 11 , 12 ]. Catalyst-free CdTe wires are therefore preferable to minimize the defect content.…”

Rapid Synthesis and Electrochemiluminescence Behavior of CdTe Nanoribbons

“…[8][9][10][11][12][13] As a kind of chalcogenides, cadmium telluride has much more technological prospects. [14][15][16][17][18] Going with the increasing interest in the nanostructured materials and nanodevices, a number of methods for the synthesis of the cadmium telluride nanomaterials with different morphologies have been developed. 19 Hierarchical assembly of CdTe nanotubes and nanowires was synthesized at wateroil interface.…”
