SHOCKLEY, W., SPARKS, M. & TEAL, G. K. "p-n Junction Transistors", in Physical Review Vol. 83, No. 1, July 1, 1951. Lancaster, PA & New York, NY: American Physical Society, 1951; pp. 151-62 in the issue of ii, 248pp. Original wrappers. This issue has been restored with a new (and reinforced) spine and spine cover, with a very strong printing of the journal name and issuea lovely job. FINE copy. The only detraction here is a small owner's rubber stamp on the front wrapper bottom. [++] "The first big change in transistors occurred when William Shockley developed a junction transistor." (This following the point-contact transistor of 1947, the first transistor ever made and built by Walter Brittain and John Bardeen; and the Type-A transistor of 1948.) [++] "The first junction transistors were sandwiches of N- and P-type germanium (germanium with an excess and scarcity of electrons, respectively). A weak voltage coming into the middle layer would affect another current traveling across the entire sandwich." --PBS Transistor Timeline [++] "After William Shockley's theories about p-n junctions had been validated by tests fabricating a working junction transistor still presented formidable challenges. The main problem was lack of sufficiently pure, uniform semiconductor materials. Bell Labs chemist Gordon Teal argued that large, single crystals of germanium and silicon would be required, but few - including Shockley - were listening. With little support from management, Teal built the needed crystal-growing equipment himself.Based on techniques developed in 1917 by the Polish chemist Jan Czochralski, he suspended a small "seed" crystal of germanium in a crucible of molten germanium and slowly withdrew it, forming a long, narrow, single crystal. Shockley later called this achievement "the most important scientific development in the semiconductor field in the early days." Employing this technique, Bell Labs chemist Morgan Sparks fabricated p-n junctions by dropping tiny pellets of impurities into the molten germanium during the crystal-growing process. In April 1950, he and Teal began adding two successive pellets into the melt, the first with a p-type impurity and the second n-type, forming n-p-n structures with a thin inner, or base, layer. A year later, it surpassed the best point-contact transistors in performance. Bell Labs announced this advance on July 4, 1951 in a press conference featuring Shockley."--Computer History Museum online [++] Shockley, Bardeen and Brattain received the Nobel Prize in Physics in 1956 "for their researches on semiconductors and their discovery of the transistor effect.".…

Terms of sale
All items are offered with a seven-day return privilege.
Right of withdrawal
If you are a consumer you can withdraw from the contract in accordance with the following. Consumer means any natural person who is acting for purposes which are outside his trade, business, craft or profession.
Information regarding the right of withdrawal
Statutory right to withdraw
You have the right to withdraw from this contract within 14 days without giving any reason.
The withdrawal period will expire after 14 days from the day on which you acquire, or a third party other than the carrier and indicated by you acquires, physical possession of the last good or the last lot or piece.
To exercise the right of withdrawal, electronically fill in and submit a clear statement on our website, under "My Purchases" in "My Account". We will communicate to you an acknowledgement of receipt of such a withdrawal on a durable medium (e.g. by e-mail) without delay.
To meet the withdrawal deadline, it is sufficient for you to send your communication concerning your exercise of the right of withdrawal before the withdrawal period has expired.
Effects of withdrawal
If you withdraw from this contract, we will reimburse to you all payments received from you, including the costs of delivery (except for the supplementary costs arising if you chose a type of delivery other than the least expensive type of standard delivery offered by us).
We may make a deduction from the reimbursement for loss in value of any goods supplied, if the loss is the result of unnecessary handling by you.
We will make the reimbursement without undue delay, and not later than 14 days after the day on which we are informed about your decision to withdraw from this contract.
We will make the reimbursement using the same means of payment as you used for the initial transaction, unless you have expressly agreed otherwise; in any event, you will not incur any fees as a result of such reimbursement.
We may withhold reimbursement until we have received the goods back, or you have supplied evidence of having sent back the goods, whichever is the earliest.
You shall send back the goods or hand them over to JF Ptak Science Books, Hendersonville, North Carolina, U.S.A., without undue delay and in any event not later than 14 days from the day on which you communicate your withdrawal from this contract to us. The deadline is met if you send back the goods before the period of 14 days has expired. You will have to bear the direct cost of returning the goods. You are only liable for any diminished value of the goods resulting from the handling other than what is necessary to establish the nature, characteristics and functioning of the goods.
Exceptions to the right of withdrawal
The right of withdrawal does not apply to:
- The delivery of newspapers, journals or magazines with the exception of subscription contracts; and
- The supply of digital content which is not supplied on a tangible medium (e.g. on a CD or DVD) if you accepted when you placed your order that we could start to deliver it, and that you could not withdraw once delivery had started.
Shipping terms
