Phosphorene discovery positively impacts 2D electronics

US researchers have made phosphorus into an analogue of graphene, dubbed phosphorene, allowing practical electronic devices made from such two-dimensional materials. Peide Ye at Purdue University, US, and his co-workers show that phosphorene is the first native 2D electron-poor – or p-type – semiconductor. That’s important for making these flat materials into standard complementary metal-oxide semiconductor (CMOS) logic circuit elements, which Ye’s team has also achieved with phosphorene. ‘For device applications it’s fundamentally better than graphene,’ Ye says.

Message from Bhagavath Geetha
  • Do not get over excited over happiness and do not get over depressed over sorrow.
  • Do not get over bonded with anyone and anybody because it can lead to problems and sorrow.
  • Never think that my duty is the topmost or lowermost. Every duty is respectful. The responsibility undertaken or given as per the position is the noblest duty.
  • Elevate yourselves, family, society and nation and never denigrate yourselves, family, society and nation.
  • We are our own closest relatives and if not properly utilised we will become our closest enemies.
  • There are possibilities of success and failure in any endeavour. One cannot assure success always.
  • Death is inevitable for everyone in this world. In any endeavour at the maximum an individual may die.
  • People may say good and also they may say bad. Approach them with stabilised mind.
  • Take anything after scientifically, logically and rationally analysing them.
  • Perform your duty, responsibility and accept the privileges eligible for you.
  • First change ourselves and then try to change others.
  • We are all instruments /tools in the hands of the nature for performing the duty. So do not think that I am doing the duty. Think that I am an instrument to do the duty.
  • Results of action may not be sweet always. Accept what ever may be the result.
  • Follow the path of great scholars who guided the world. Listen their messages.
  • Results and rewards will come and go but stick to your duty with devotion, dedication and sincerity.
