TOTAL ENERGY CALCULATION OF AlAs AND InAs BINARY SEMICONDUCTORS USING THE PROJECTOR AUGMENTED WAVE METHOD

The total energy of an element is the basic energy value from which other properties of the element can be calculated. Aluminum Arsenide (AlAs) and Indium Arsenide (InAs) are III – Arsenic binary semiconductors with indirect and direct energy band gap respectively. The total energy of each of them was calculated using the Projector Augmented Wave (PAW) method with the PBE-GGA for the exchange-correlation functional. The total energy were calculated and from the results gotten, the la...

Recycling of water sachet

ABSTRACTWastes generally render our environment unfriendly and the worst of them all are those wastes that are non-biodegradable and as such, wastes of these forms (non-biodegradable) pose a serious threat to our environment.One of these categories of non-biodegradable wastes is pure water sachets. They are found in virtually every part of Nigeria and various attempts have been made to biodegrade these pure water sachets. One of these attempts was carried out byNwachukwu S.et al (2010) in the...

DESIGN AND CONSTRUCTION OF A TWO-DIGIT DIGITAL COUNTER

ABSTRACTIn this work, we designed and constructed a digital counter circuit. The initial design criteria for the project were: to have a two digit output, to have the circuit count from 0-99, to include either a 555 timer or manual counter. Research was conducted into similar analogue electronic circuits and a suitable point of a digital die was identified. The digital counter circuit was designed using BCD 4506 binary counters and 7-segment display outputs. The circuit was modeled using prot...
