Ingin sedikit berpromosi mengenai publikasi penelitian terbaru kami. Mudah-mudahan bermanfaat dan dapat berguna bagi komunitas luas di Indonesia. Mohon mensitasi jika ada yang melakukan pekerjaan yang berhubungan. Yang pertama berhubungan dengan topik organik transistor, optoelektronik, fotonik, dan laser. Yang kedua mengenai transistor carbon nanotubes dan polimer. Keduanya juga erat berkaitan dengan pengembangan sel surya berbahan organik dan juga carbon nanotubes. Jika membutuhkan isi lengkap publikasi #2 dikarenakan tidak memiliki akses ke jurnal tersebut, silakan hubungi saya. Akan saya kirimkan via japri.
==== Organic Single-Crystal Light-Emitting Transistor Coupling with Optical Feedback Resonators Satria Zulkarnaen Bisri,et al. Scientific Reports 2, 985 (2012) Organic light-emitting transistors (OLETs) are of great research interest because they combine the advantage of the active channel of a transistor that can control the luminescence of an in-situ light-emitting diode in the same device. Here we report a novel single-crystal OLET (SCLET) that is coupled with single crystal optical feedback resonators. The combination of single-crystal waveguides with native Fabry-Perot cavities, formed by parallel crystal edges, drastically lowers the threshold energy for spectral narrowing and non-linear intensity enhancement. We apply this structure to SCLETs and demonstrate the first fabrication of a SCLET with the optical feedback resonators. ===== High Performance Ambipolar Field-Effect Transistor of Random Network Carbon Nanotubes Satria Zulkarnaen Bisri, et al. Advanced Materials 24, 6147 (2012) Ambipolar field-effect transistors of random network carbon nanotubes are fabricated from an enriched dispersion utilizing a conjugated polymer as the selective purifying medium. The devices exhibit high mobility values for both holes and electrons (3 cm2/V·s) with a high on/off ratio (106). The performance demonstrates the effectiveness of this process to purify semiconducting nanotubes and to remove the residual polymer. Juga cover untuk edisi ini merupakan bagian dari paper ini. http://onlinelibrary.wiley.com/doi/10.1002/adma.201290292/abstract Selective purification of carbon nanotubes using conjugated polymers is utilized on page 6147 by Maria Antonietta Loi, Satria Zulkarnaen Bisri, and co-workers to fabricate high-performance ambipolar transistors. A device of drop-casted random-network nanotubes demonstrates high carrier mobilities and high on/off ratios for holes and electron accumulations. Together with the optical measurement results, the performance of the transistor indicates the purity of the nanotube dispersion with minimum residual polymer. ==== Dr. Satria Zulkarnaen Bisri
