Special Issue Information

Dear Colleagues,

Recently, various optoelectronic devices such as light-emitting diodes, photovoltaic cells, and photo-detecting devices have been developed to be applied as wearable implements. For these applications, the device properties should not degrade during device bending or stretching, and materials such as semiconductors, dielectric materials, and electrodes should display high transmittance in the visible range for high-efficient light extraction. It is very important to design materials with high mechanical flexibility and optical transmittance, while maintaining their own electrical properties. This Special Issue seeks to showcase research papers, short communications, and review articles that focus on materials such as source, drain, gate electrodes for driving thin-film transistors, electron and hole transport layers, and anodes and cathodes for optoelectronic devices. We are also interested in works dealing with various technologies such as doping, post-treatment, and bandgap engineering to improve the conductivity and transmittance of materials.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Micromachines is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Hybrid quantum dot light-emitting diodes (QLEDs) with no buffer layer were developed to achieve white emission using red quantum dots by spin-coating, and blue phosphorescent organic molecules by thermal evaporation. These unique bichromatic devices exhibit two distinct electroluminescent peaks with similar intensities at 10.5 V. For white emission, these hybrid QLEDs present a maximum luminance of 6195 cd/m2 and a current efficiency of 2.02 cd/A. These results indicate that the unique double emission layers have the potential for bright and efficient white devices using fewer materials. Full article
