Recently, it has fueled the rapid growth of the study in two-dimensional (2D) crystals. Their unique properties should lead to a possible breakthrough in the semiconductor industry. In our group, we are focusing on the design and fabrication of novel devices based on ambipolar 2D crystals, in which the major charge carriers can be tuned by electrical field. We have developed such crystals for programmable nonvolatile p-n diodes, programmable nonvolatile ambipoar Schottky diodes, ambipoar memories, and so on. These devices exhibit excellent properties different from the traditional units, which have been exploited for dual-mode nonvolatile memories, memory inverter circuits, logic rectifiers, photovoltaics, logic optoelectronic circuit, optoelectronic memories. Such units may lead to a possibility for innovations in electronics and optoelectronics, and become ubiquitous structures in the future circuits.
