2 μm solid-state laser mode-locked by single-layer graphene

Alexander A. Lagatsky, +11 more
- 10 Jan 2013 - 
TL;DR: In this article, a 2'μm ultrafast solid-state Tm:Lu2O3 laser, mode-locked by single-layer graphene, generates transform-limited ∼410'fs pulses, with a spectral width ∼11.1'nm at 2067'nm.
Journal ArticleDOI

Complementary Logic Gates and Ring Oscillators on Plastic Substrates by Use of Printed Ribbons of Single-Crystalline Silicon

Dae-Hyeong Kim, +8 more
- 01 Jan 2008 - 
TL;DR: In this article, a CMOS inverter and three-stage ring oscillator were formed on flexible plastic substrates by transfer printing of p-type and n-type single crystalline ribbons of silicon.
Journal ArticleDOI

Bendable integrated circuits on plastic substrates by use of printed ribbons of single-crystalline silicon

Jong Hyun Ahn, +12 more
- 21 May 2007 - 
TL;DR: In this paper, the authors present studies of several simple integrated circuits (n-channel metal-oxide semiconductor inverters, five-stage ring oscillators, and differential amplifiers) formed on thin, bendable plastic substrates with printed ribbons of ultrathin single-crystalline silicon as the semiconductor.
Journal ArticleDOI

Bendable GaN high electron mobility transistors on plastic substrates

Keon Jae Lee, +6 more
- 20 Dec 2006 - 
TL;DR: In this article, a procedure for fabricating flexible forms of high electron mobility transistors (HEMTs) supported on plastic substrates is described, using a combination of conventional top-down, wafer scale fabrication protocols to define a printable form of ultrathin, device quality multilayer AlGaN∕GaN single crystalline microstructures.

Stretchable Active Matrix Inorganic Light-Emitting Diode Display Enabled by Overlay-Aligned Roll-Transfer Printing

Minwoo Choi, +7 more
- 01 Mar 2017 - 
TL;DR: In this article, an active matrix-type stretchable display is realized by overlay-aligned transfer of inorganic light-emitting diode (LED) and single-crystal Si thin film transistor (TFT) with roll processes.
