Abstract
The great moment of fame for germanium was in December 1947. In that year the first transistor was made by a research team of Bell Laboratories. Owing to some problems with germanium, it was soon supplanted by silicon. Currently, germanium is still used in the microelectronic industry for opto-electronic and solar electric applications, but its role is very minor compared to its big brother silicon. After the rise of graphene, germanium received renewed interest because of the predicted stability of the graphene-like allotrope of germanium. Germanene, the germanium analogue of graphene, shares many properties with graphene, but there are also a few interesting differences that makes this material very appealing for device applications. In this contribution, I will give a brief historical overview of germanene, discuss the pros and cons of germanene and elaborate on its potential for future device applications.
期刊介绍：
Surface Science is devoted to elucidating the fundamental aspects of chemistry and physics occurring at a wide range of surfaces and interfaces and to disseminating this knowledge fast. The journal welcomes a broad spectrum of topics, including but not limited to:
• model systems (e.g. in Ultra High Vacuum) under well-controlled reactive conditions
• nanoscale science and engineering, including manipulation of matter at the atomic/molecular scale and assembly phenomena
• reactivity of surfaces as related to various applied areas including heterogeneous catalysis, chemistry at electrified interfaces, and semiconductors functionalization
• phenomena at interfaces relevant to energy storage and conversion, and fuels production and utilization
• surface reactivity for environmental protection and pollution remediation
• interactions at surfaces of soft matter, including polymers and biomaterials.
Both experimental and theoretical work, including modeling, is within the scope of the journal. Work published in Surface Science reaches a wide readership, from chemistry and physics to biology and materials science and engineering, providing an excellent forum for cross-fertilization of ideas and broad dissemination of scientific discoveries.
