This review paper describes some of our recent topics on surface functionalization of IV semiconductors. Well-designed surfaces of the semiconductors create exciting opportunities for technological applications. To meet such exciting functionality, we use a monolayer system in which the reactive monolayer attaches to the semiconductor surface via covalent linkage. Most importantly, this molecul...

The electrical properties of grain boundaries are very different in insulators, semiconductors and metals. We present them briefly in the case of insulators and semiconductors and with more details in the case of metals.

The objective of this paper is present the data requirements for modeling power electronic devices to aid in modeling power converters for transient simulation studies. The presentation will target applications of power semiconductor devices commonly used in medium to high power applications: insulated gate bipolar transistors (IGBTs), Thyristors (SCR), and Gate TurnOff Thyristors (GTOs) and po...

Silicon may be unable to continue serving as the backbone for future technologies. The search for silicon replacements has led to the investigation of thin 2-D materials. Some of these materials are single layers of group VI transition metal dichalcogenides. Through mechanical exfoliation, these materials can be isolated and used to construct monolayer field effect transistors. A transfer proce...

History With the invention of the transistor around the middle of the last century, inorganic semiconductors such as Si or Ge began to take over the role as the dominant material in electronics from the previously dominant metals. At the same time, the replacement of vacuum tube based electronics by solid state devices initiated a development which by the end of the 20th century has lead to the...

Charge carrier dynamics in amorphous semiconductors has been a topic of intense research that has been propelled by modern applications in thin-film solar cells, transistors and optical sensors. Charge transport in these materials differs fundamentally from that in crystalline semiconductors owing to the lack of long-range order and high defect density. Despite the existence of well-established...

The band ordering of semiconductors is an important factor in determining the mobility and coherence of the wave function of carriers, and is thus a key factor in device performance. However, in heavily doped semiconductors, the impurities substantially disturb the band ordering, leading to significant degradation in performance. Here, we present the unexpected finding that the band ordering is...
